Audio synchronization

Hello
In version 3.3.3 I can synchronize a track without any problems.
However, since version 3.4.0, I started to have a problem when synchronizing tracks. Namely, the message pops up: the content you are trying to paste will span across more tracks than you currently have available
Here are video examples:
Version 3.3.3
Version 3.7.0

Can you tell me how to fix this?

Here’s a step by step of what I’m doing:
I load 2 tracks and find the number of samples to sihnronize. Then, I want to insert the required number of samples into the second track, but I get an error. In version 3.3.3 there is no such error and that’s why I still use it.
