JSON API : Files added using the ReviewService.addFiles are loaded in the wrong order

Hi,

I'm trying to create a plugin for my IDE. When I specify "baseVersion", the files are loaded in the wrong order. When I again update the materials review, the situation becomes worse:

As a solution, I no longer specify "baseVersion", and send the versions in the right order in different requests. But now I can't see the correct information about added/deleted rows - all rows are considered to be added:

Is this an error or am I doing something wrong?
