Hi Umesh,
Thank you for reporting this bug. I am familiar with it, but have not yet been able to identify what causes it to happen. However, I found that it seems to be tied to the project itself, so it will probably keep happening with that specific project (and any other affected project) but you might still have projects for which it doesn’t happen. What you can try to do is duplicate your project and see if the problem persists with the copy. If not, I’d say keep working on the copy
