I use number for my audio or projects file , but in media, after pressing name button for listing numbers , the order of the numbers is wrong , there is after number 1, number 10 instead of number 2 , or after number 2 is number 20 instead of 3 , And so on .
There is this bug for audio and midi files and mix down too .
I have added one screen shot for this bug to this report.
