Trying to create an entry and exit point and having problems

When I set the in point, the in point appears in the playhead position, but the out point is one more frame than the playhead. This problem has not happened before. Is there a way to solve this problem? Thank you for helping others!

English is not very good, please forgive me.

It's called an inclusive out point. This is how pretty much all NLEs work. It's not a bug it's a feature.

Can I set the out point to the same position as the playhead? Thank you very much for your answer.
