Duration calculation for a marker time range is different on timeline vs. when editing marker

Bug
1

  • What is your operating system?

I’m reporting this on macOS Sonoma 14.8.4, but I suspect this is not a platform specific bug.

  • What is your Shotcut version (see Help > About Shotcut)?

Shotcut 26.2.26

  • Can you repeat the problem? If so, what are the steps?

I have a marker range, and mousing over (first screenshot), it’s showing what I believe is the correct duration of 1 minute, here. In the marker editing dialog window (second screenshot), the start and end times are correct, but the duration calculated is different. I’m guessing this one is incorrect and off by an added frame (60 FPS project).
