There is nothing wrong.
99% of times the compression algorithms are available in multiple implementations (libraries and software) and multiple settings, obviously zlib is one of them.
So it's perfectly normal and there are no negative effects on the reimporting operation.

In your specific case I see a possible problem with the CRC fields available in the format of the archive because the game may check both the compressed and uncompressed archived file, and if one of them is different then the archived CRC value it will refuse to work.
Obviously the reimport mode doesn't touch the crc fields (or any other field) so if your game doesn't work with the edited archive (even if you didn't touch the imported file) then this is the reason.
