QB Issue Resolution:
This is a known issue with pro, intuit says they are working on it, well they said that several months ago
All you can do is wait for a fix, while waiting …
In Desktop, back up the file then use the main menu File>Utilities>Rebuild and Verify run it as many times as necessary (but at least 3 times) until it completes, then close QB and re-open it and see if it helped
And try entering the bill, then paying the bill for inventory items
