I am sorry, but it's not clear what you want or what is the problem.
For example the RAR archive has TWO versions for episode S05E01, one called ~CiELOS and the other called ~Gerald
The ~CiELOS version is exactly the same as the one already uploaded here:
https://www.opensubtitles.org/en/subtit ... ode-5-1-de
So, if you try to upload this ~CiELOS version, you will get an error like
"this subtitle already exists", because... it already exists.
Uploading the ~Gerald version as update v2 should not be any problem. Have you tried?
I see uploading a v2 did work for episode 8:
https://www.opensubtitles.org/en/subtit ... ode-5-8-de
I suspect you just make some mistake with confusing versions...
Concentrate, focus... and try again
