There is an Error in the Bundle for Upgrading 7.5.0 to 7.5.4. The DB-Tables for the Secured Actions will be created, but the data for the Secured Actions won't. Workaround: First install the Bundle 7.5.0 to 7.5.3 then Upgrade this state of SLX to 7.5.4 with Bundle 7.5.0 to 7.5.4. Now everything should be working fine.
