Bug - Normal I can't use a variant.

[mrlemonxd]

Hello! I come to ask for a solution to a problem that occurred to me. I have a variant, (Silent kill), that I cannot use in battle or deployment. It seems to me that it is locked, like it is in deployment, but no. I reinstalled the game but it is still the same. I hope you can help me.
My cell phone is Samsung Galaxy J2 prime, android 6.0.1
sorry I do not speak english. This is from google translate
Thank you!

This is fixed in our latest 4.3.3 update but you'll still need to 'unlock' any currently stuck fighters. Please send a ticket to skullgirlsmobile.com/contact with your info and we'll look into it!
