Sometimes the game bugs out in the mechbay, and the cursor will start rapid tapping one of the mech slots. This happens on PC, PS4 and PS5, so imagine it happens on Xbox as well. I opened a ticket with them and reported the bug, along with several other persistent bugs about 7 weeks ago. They gave a generic response that it would be looked at. Guess they're still 'looking'.

Yes, it seemed to push button rapidly many times as you said. You had already informed this matter to company! I only wondered if my Steam Deck had key drift, but don’t have serious matter. it seems software matter, isn’t it. Thank you！

Yep, it's just the game being buggy.

Some of the other bugs I reported, that likely aren't going to be fixed are:

There's a glitch in painting mechs where colors may refuse to update. This doesn't seem to be fixed by reloading the save, either, and may have to be forced to work by continuing to mess with color/pattern swaps to 'wake up' the system.

There's an issue with missions that have multiple missions in the contract. When you finish one mission and return to the mechbay, if you swap one of the 4 active mechs out for another one, it may glitch out and will refuse to allow you to 'deploy' when the ready meter hits 100%. You have to save the game, return to the main title menu, then reload the save to continue..

Once in a long while, an Ally mech in your lance may get stuck on invisible terrain and won't move at all. You have to manually change to them, move them out of the way of the invisible obstruction, and then can switch back to your selected mech. This happens very rarely, but if you notice an ally mech is lagging behind, chances are they got stuck like this and need to be 'woken up' this way.
