Mouse 5 and Mouse 4 thumb buttons

Hello, I recently remapped my ping button to mouse 5 and then my crouch to Mouse 4, however Battlefield 6 (BF6) is picking both up no matter which thumb button I depress. 

For instance if I were to click Mouse 4 to crouch it would crouch but also ping at the same time as if I clicked both inputs, and the same is vice versa. Any fixes?
