[BUG][PROTOTYPE] Can't change transitions' duration

I'm linking transitions in a project and sometimes I need to change its' duration but sometimes Adobe XD just don't let me do it. I type the new value and press enter, but the number goes back to the original value. This doesn't look like a technical rule, but a bug.

It happened before in other files.

Can't share the file.

Won't collect logs.

Windows 10, latest XD version.
