@kjz posted this issue at:
https://community.quicken.com/discussion/7861032/category-merge-bug Their post was subsequently closed by
@Rocket J Squirrel because they couldn't reproduce the problem. I have reproduced the bug and the workaround that
@kjz provided also worked for me.
In the Category List, when I right-click on a category that is IN USE the option to merge is not in the drop-down menu. When I select Delete, then choose "No", then right-click on the category again then the Merge option appears.
I am using Windows 10 (fully updated) and Quicken Deluxe year 2020, version R31.5, Build 27.1.31.5.
