have you maxed turbo cyclaw level? I heard that there was an error that the game not allow you to use turbo cyclaw as material to fuse 6* ultor if you maxed its level.

Or more simple reason, did you mark turbo cyclaw a favorite unit? if yes,remove the favorite, it will allow you to use in the ultor fusion
