perhaps a severe inconsistency?

Hello friends, I am reporting for the proper functioning of the game, I am studying the game and I found a serious inconsistency, which can be taken advantage of improperly. with a mercenary skill, which is called emergency reloading that imbues your attacks with more damage, I could notice if I open the skills panel and unequip any support it does not respect the skill's charging time and thus can imbue several shooting skills, is this correct?https://youtu.be/A8olnsfZvq8
