TX speed up not working randomly

Occasionally when I send a TX, I try to speed it up. This only occurs some of the time, but for some reason, the speed up does not work at all(The GWEI does not change). On top of this, it removes the ability to speed it up again, from either location where one would click the button to do so. This problem occurs both on my regular wallet and hardware wallet. I previously encountered this on the latest version, and reverted to try and avoid it, but it still occurs on this version too.
