Updating my online experiment after creating a project

Ok, so, I have an active experiment now uploaded. It works, though I can’t get any data because of the colon issue. But, now I can no longer sync my experiment to the one that is online. When I try to run it online through psychopy, I get a message saying:

This file doesn’t belong to any existing project.

I can sync the root folder through Pavlovia, but the changes that I made to the experiment do not get pushed to gitlab.

Am I doing something wrong, or is there no way to update .psyexp files once they are uploaded?

I’m not sure how syncing works. I’ve just tried adding an excel and word file to the root folder and then tried to sync. Those two files were not pushed to gitlab. No idea whats going on.
