Uncommitted changes shown when trying to upgrade workspace

Hi Team,

We were trying to upgrade our workspace which was created with the project during 24C and currently we are in 24D using the given link:

We followed the instructions and we could see a message that the migration was successfully completed similar to the one seen below. There was a commit button which we did not use as it was not mentioned in the document and we closed the application migration window. Post that, we saw another window pop-up which mentioned there were uncommitted changes and prompted us to commit the same (as seen in the below image). But this wasn't expected because prior to using the migrate option(as per the above link), we published all changes and there were no changes/customizations done in between.
