I second this line of thought. I would say that @Amir2269673222x1 has one checkbox too many on imports. I assume that this is from screen capture. If so, check the export settings and mirror the setting on import. I know you may do this all the time but one check bok by accident can make that happen.
Sorry. We'd need more info on the clip properties. What are they? In the Project panel, right click on the clip in question and choose > Properties. A screenshot helps. We also need a screenshot of your sequence settings. These two things, ideally, should match. If not. let's make sure your sequence settings are correctly set up.
Awaiting your input so we can help.
Thank You,
Kevin
