Gltich happens quite often when you have two of the same skill of the same rank on a weapon.
Dude X wrote:It's not bugged, that happens because the skills that can evolve are stored in different variables from the ones that can't so you end with some duplicated.
Funny fact - the skills that can evolve seem to end with a bit more force power when compared to the ones that can't, like a small reward in damage for the hard work to get them evolved [I can't say that this happens with every single skill because I haven't checked them all [ofc...] but the few ones that I've have like 30 more power when compared to the ones that can't].
Storing them in different variables would not cause it to show up twice in your skill list. However, it's possible that the same pointer had been assigned different memory locations. That is, due to some sort of error, the skill registered with a different if-clause than it was supposed to, and ended up inserting a new skill into the list as opposed to accessing the one currently in the list.
By that means, it's still possible to access the other skill in the list, because it's the list that is misprocessing the memory locations as opposed to your weapon, depending on what type of function was written to access the list. (For example, Momotarou would be able to access it as he appears to have a search function that finds literally everything.)
Furthermore, where is that observation coming from? The skill force on the nth rank of a skill has nothing to do with whether or not there is an n+1th rank of the skill. There are many skills that completely contradict what you've stated here.

The different variables can be proved if you extract both skills from different weapons with same rank and try to add each other to the opposite weapons.
For example, I extracted 1 evolved Flying Lighting Strike - V. I clicked at the card with it and added the evolved rank V into a weapon with one non-evolved Flying Lighting Strike - V. Usually you would think that the game would reject it, right? Wrong, the game accepts it fine. The same applies to a non-evolved rank V skill, or any level, to a weapon with a evolved rank V, the game thinks that the skill is different and you can try to the skill there.
Why you've 2 skills of rank VII I don't know because Momo only let's you to evolve skills to VI afaik but, maybe, it's because the skills from cards are different, in terms of variables, from the ones we get from weapons?
If you're going to ask the staff, only the programmers would no why it would happen. Of course help desk is not going to give you an explanation, since the level of understanding that helpdesk has of the code is often not very high.
Like I stated above, different variables is not nessecarily true. Again, with the type of data structure that they use, I would be more surprised if either of them had a unique variable in the first place considering how efficient a list or array would be. It makes effectively no sense to define a variable for each and every skill when you can easily get by without doing so.
No one said you can't have multiple of the same skill on a weapon.
