Issue Summary

Switching from Advanced to Basic JQL search on Epic Link a results in incorrect results when using "Is Not Empty"  advanced operator 

Steps to Reproduce

1.  Login to Jira Data center
2. Create test Software project.
3. Create several test issues, ensuring they include an Epic Link.
4. Use Advanced Search with a query like "Epic Link !Empty"  or " is not EMPTY" to view
5. all issues with an Epic Link. (Observe the result)
6. Switch to Basic JQL search and click search 

Expected Results

 Jira should disable the Basic search button after searching with the advanced operator.  

Actual Results

The JQL query has changed to "Epic Link is Empty"  when switching from advanced JQL to Basic search 

When using advanced search functionalities, Jira should deactivate the basic search button. This prevents situations where the basic search cannot accommodate the current advanced JQL structure and cannot convert it back into basic search options.

Workaround

Avoid switching between advanced and basic search when using advanced operators like "is not".
