Mark export not working

What is your operating system?
Windows 10 64bit

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
22.6.23 64bit

Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
I made a mark and extended long enough I wanted, and then exported. But Shotcut exported the entire video. Say the entire length of my video is 1 hour and what I marked is 30 minutes. Although I set the export from the marker, Shotcut still exports it as 1-hour video.

Unable to reproduce, maybe not enough information. And “latest” for version is not acceptable for a bug report.

Hi, sorry for the inconvenient. I just fixed the version info you mentioned.
What kind of info do you need more? I think I did my best to explain it.
