PS5 Controller Buttons Preset

While customizing my own button presets, I ran into a small issue. I switched to alternative button layout, which swaps the melee and crouch buttons from R3 to O. This also switches the other functions of these buttons but I'm mainly concerned with crouch, melee, and mounting. While in alternative button settings, when I use "O" for melee while standing up, it will simultaneously melee and change my stance to crouch. Using "O" for melee again while crouched will simultaneously melee and change my stance to standing up. Lastly, mounting in alternative button settings. While aiming down sight and pressing "O" to mount my weapon, the game will change my stance instead of mounting. In conclusion, it seems that the alternative buttons setting will indeed switch the functions of the Default R3 and "O" buttons. However, in alternative settings, R3 and "O" both are acting as a crouch button instead of just R3 being crouch. This causes the functions for the "O" button on alternative settings to be both melee and crouch. In this case it seems mounting is unusable and melee will also change the stance you're currently in. I've tried to map these button functions in custom button mapping to be identical to the alternative setting except this time it is custom button settings since I did it myself instead of the preset. The end result gives me the same problem. "O" still acts as crouch even though my custom setting says crouch is R3.
