Hello Hammed,
Happy to help!
If your course is not working properly in your LMS, one troubleshooting step that you can do is to test it in another LMS to isolate if the behavior is LMS-specific. You can use SCORM Cloud for this. You'll also want to make sure that you are publishing your course according to this article:
If you can replicate the resume issue in SCORM Cloud, please share a copy of your project file here or in private by opening a support case so we can take a closer look at what's happening. We'll delete it when we're done testing!
