Hi Vusal,
RS2 uses a standard form of RINEX without any modifications, so there should not be any issues with its compatibility with any post-processing software. I’d recommend checking out what might be wrong with the data import with the software provider.
We’ve also just released a new stable version of the firmware - 2.24.0. Among the lots of improvements, it resolves the bug when in some cases two identical logs were downloaded. Here is the guide oh how you can update your RS2.
