SUMMARY The problem occurs on an old kmy file last use with 5.1.3 version and open with the 5.2.1 version. Tags not displayed for most operations in the ledger and not used in the report "transactions by tag". STEPS TO REPRODUCE 1. Open a 5.1.3 file in a 5.2.1 version of KMM. The file contains some tags and operations with these tags. 2. In the "tags" view, we can see the operations linked to the tags 3. Double-click on an operation in the list : the tag does not appear 4. Create a "transactions by tag" report. The tags are not used OBSERVED RESULT The tags linked with a transaction in the 5.1.3 version are not taken into account by the new version for all functionnalities. EXPECTED RESULT All the tags linked with a transaction in the 5.1.3 version must remain linked with the new version for all functionnalities.
