The table that lists the certificates in the truststore can be sorted. Some cells have a color.
When you sort the table differently, the wrong cells are colored.
Not only colors are wrong but also wrong certificates are displayed after opening them. It appears that table sorting is disconnected from certificate sorting. In effect when table is sorted list of certificates isn't. Sorting is now temporarily disabled.
Still an issue?
Still it is, so sorting is disabled. After merging it might be easier to fix this issue.
