Getting Qty mismatch between POS and various Stock Reports ERPNext V14

I am facing problem in Item Stock Qty.

In POS the Qty of an item shown does not match with the Qty of that same item in various stock reports.

Here are a few screen shots of POS and various stock reports.

What must be the problem and how to resolve this issue?

Sorry to bump the post.

I am still stuck and cannot find any solution to this.

Finally I found the problem!

It seems that POS skipped creating related Sales Invoices for a few POS Invoices.

I don’t know why this has happened.

Has anyone faced similar problem?
