WordPress Theme Rejected For Things I already fixed

Hii, my WordPress theme has been rejected over things that I already fixed before.

For example my theme put out HTML code and I fixed the issue and resubmitted my theme. Today I got a message that my theme still outputs raw HTML and the reviewer sent me a screenshot again. I was surprised, because I really thought I fixed the issue. So I checked my theme again on my WordPress installation, I checked the same comment of the theme test data of which the reviewer sent me a screenshot and there was no HTML output whatsoever.

Anyone ever had the same experience? Could it be that I have to increase my version number every time I resubmit a rejected theme?

Any help would be very much appreciated! Thank you very much.
