Hi Jiří Prajzner

Thank you for your question.

While I do struggle to visualise what you are referring to, please do allow for me to confirm that the overall settings of the package/project could be different.
So when you are comparing project settings from import 1 to import 3, we cant assume they will be the same. 

Its not just the extra languages and files that get updated, its the entire project.

Hello, thank you for replying!

I compared project settings (in .sdlproj files). I copied them to word and used function compare. I can see there are only changes in GUID, target language and analysis.

I understand when I upload the second (or third etc.) package, the entire project is updated and the final settings are taken from the last uploaded package. But I think it is a strange behaviour that TMs are also updated and that TMs from previous packages disappear.

However, I'm not sure how the customer creates the packages. I just wanted to ask if this is correct behaviour of Studio or if there is some mistake in creating packages on the customer's side and find something we can recommend him to do.
