masking tool question

Hello,

I am sculpting my model, and the part is boots.
I used masking and made some patterns on the boots, then use inflat to give some effect.
Now, the right side boot is correctly done, but the left side boot has opposite effect.
If it’s my uv map mistake…how can I correct it?
If it’s not the uv map, then how can I correct it?
Thank you.

NVM, I found the reason.
I didn’t flp the uv when I mirror copy them.
