Trying to cast skills with no cost

[UltraB64]

I'm currently working on a project that involves lots of different characters and playstyles. One character will have battle skills that they can use without the cost of HP, MP, or TP. They'll instead opt for a cooldown system (which I'm using Yanfly's Skill Cooldown and Skill Core for) so that they can use a skill at the cost of having to wait to use it again. Problem is when I set the skill to have no cost at all, it becomes grayed out and therefore unusable. Anyone know how to work around this?

i also have yanfly skill cooldowns and limited use skills that have no costs but never had grey'd out issues. are you giving these skills some other restriction like weapon type?
can you post a screenshot of the skill and class thats using it

Oh, I feel really dumb now.
I was importing things from a previous project over and forgot to give one of the new actors a weapon with the type that the skill would use. So they while they had the skill, they didn't have the appropriate weapon type to use it.
Thank you so much for figuring this out with almost nothing to go with.
