Steps to reproduce the issue

I update my articles integration to modern from legacy.. however only the links i recently anchored/linked-up are displaying correct url.

I did create menu items for the categories in which the articles are assigned

Expected result

If i link now, it will show this link...

Actual result

This is what it appears for links i had earlier linked up.. (IF I UNLINK MANUALLY AND LINK AGAIN, THE URL STRUCTURE CHANGES TO ONE ABOVE)

System information (as much as possible)

joomla 3.8.5

Additional comments

Is there a way I can update all the links from the bad old version to new correct ones automatically and not manually?

Thanks.....
