🐛 Bug Report

When I solved a problem in other places or when new problems have arrived, clicking the refresh button could not show the right status of the problem(the problem I solved in other places is still in an unresolved state in the explorer) or get the new problems. After I delete theproblems.json in the cache directory manually, the behavoir of this extension is in line with expectations.

To Reproduce

1. solve a problem in other places.
2. click the refresh button.

Expected behavior

The status of all problems should be right and the list of all problems should be complete.
