I’m sorry for the delay.
We have tried to reproduce the issue with no success.
Maybe we are doing differently.
I have couple of questions:
1. if you select both two recording to import does both two recording has a correct size?
2. In your workflow the second recording all the time shows up as an incorrect size? All the time show the same (incorrect) length? If yes what is the size/time of the file?
3. Are those 24ch/48K/24 bit recordings?
4. Do you have a same issue if the recordings are shorter than one hour?
