Right‑click marker handle, and choose Convert to Range. Problem.

[Shortend]

Right‑click the marker handle, and choose Convert to Range not working on Marker 01. Marker disappears.

Marker 02 and higher work as they should when converting to range. I've tried on different files and same result.

Suggestions?

Thanks.

It definitely works fine here on a PC - just the same as any other marker; it creates a small range to the right of the marker that you have to extend appropriately. The only way I can get it not to convert to a range is to place the marker at the very end of the file (which is reasonable, considering that it can only extend into the future), but if you drag it back, it then behaves the same as any other marker, and you can turn it into a range.
