When using "is a" on the Class field in a filter on a table that uses sys_class_path, after the query is run, the bread crumbs change from user friendly labels and values to system stored values referencing sys_class_path instead of Class
Steps to Reproduce
This can be reproduced in Jakarta, Kingston, London and Madrid
1. Go to cmdb_ci.list
2. Click the Filter button and select Class -> is a -> AD Domain and hit Run
3. Observe that the Filter displays with Sys class path is a /!!/!(/!3/!6% ( as shown in the attached screen shot)
As a workaround, you can open the filter builder, where you can see the real value.
