Frost Wall cannot be cast/vanished from skill slots - bugged additional info

I lvlup Frost Wall into lvl 15 (and i was trying to switch opition "Used with weapon set", then skill got bugged - it vanished from skill slot(cannot cast it, cuz skill vanished) + info in Skill menu (additional info) says only: "This information is currently unavailable".

I test it with new skill (new uncut gem) and it work, But old one still is unusable.

Menu with bugged skill: https://ibb.co/X4rHDZ6

After one day, and switching gems, skill repair itself.

I experienced this issue as well, it happened when I leveled up my Frost Wall to level 11, however I was using a weapon with +4 to cold spell skills so it was technically also level 15 I suppose.
My skill details looks bugged in the same way as the original posters link.

Unequipping the weapon with +skill levels didn't fix the issue, neither did leveling up the gem to level 12.

The only way I found to get it to work again was to create a new lvl 10 Frost Wall from an uncut gem, which was kinda unfortunate as it was the only spell that I had added an additional support link to which of course did not follow to the new gem.

I think I might be having the same issue with 2 skills.. and I was using the skill menu to assign skills to differ weapons..

Did you keep the broken skill in your skill menu or bags or stash before it fixed itself? Maybe ggg is manually finding and fixing these..
