If i run Replay Gain in the Tag editor and save it and play the mp3 in AIMP nothing has changed in the sound level (I can see it on the VU meter and hear it), but if i instead run the same mp3 file in the old MP3Gain program it will change the sound level in AIMP.
What i understand AIMP will add the information in the beginning of the file and MP3Gain at the end of the file and AIMP seems to ignore what itself has add, but follow the MP3Gain information.
After running the mp3 file in AIMP i can see a value in the Track Gain (dB), but it is empty after running the same file in MP3Gain.
Of course i started from a file without any Replay Gain in both cases.
So, why will AIMP ignore the information it adds, but follow MP3Gain?
Maybe i do something wrong, but what should that be?

MP3Gain changes the volume in audio frames (lossless, usually reversible).
AIMP uses tags, but you need to enable this feature: Sound Effects > Volume tab

…also writes 'Gain info" into APEv2 tags (https://mp3gain.sourceforge.net/faq.php#tagprobs) of a file.mp3 when dropped into mp3gain.exe, but then this file has "No undo information" (analyzed only, modified its timestamp)… AIMP always displays ReplayGain - / - for those mp3 files (analyzed_with_mp3gain || modified_with_mp3gain), because they have no ID3 "Replay Gain" tag, so, run a command line mp3gain /p /s d "for those analyzed.mp3" "or even modified.mp3" "and etc.mp3" files.mp3 ;D

Tried a (re)placing MP3Gain info (with)into ID3v2 tag with /p /s i switch on version 1.5.2:
RVA2: "track" [00] + 6 bytes
TXXX: 'MP3GAIN_MINMAX" [00] + decimal digits, comma, decimal digits… :\
