Publish tracks with different codecs not working

[thepacketloss]

when I publish 3 tracks with different codecs all three tracks will publish with the codec of first published track.
I mean consider I want to publish 3 tracks like these :
Track 1 with AV1
Track 2 with VP9
Track 3 with VP8
all 3 tracks will be published with AV1 codec
and if I change the order of publish like this :
Track 1 with VP8
Track 2 with VP9
Track 3 with AV1
then all 3 tracks will be published with VP8 codec.
I tested these scenario with python sdk and there was no problem with that and it happens only with rust sdk.
