Format-on-save open the same file in popup

[koptan]

When I do save my buffer I am doing format-on save and I see the error message in rustic-complication mode window, which is good, but when I fix all the issues in my code and make it work and save it again, in rustic-complication mode window it's opening the same file that I am working on it, because there is no errors !!

any solution for this behavior?

Screenshots:
Here I can see the error in popup ... all good:

Here in same popup after fixing all issues in my code, it's just opening the same file !!
