Answer
Both symptoms point to the same class of stale-cache issue and share the same fix. Refresh the Language cache and the Dictionary cache from IEE first, then log into the Aurena client and clear two additional caches directly via the browser URL: append /main/ifsapplications/projection/ClearCache?METHOD=CLEAR_PROJECTION_CACHE&VALUE=* after the 'main' segment of your Aurena URL and hit Enter (it returns nothing, which is expected), then separately append /main/ifsapplications/web/server/clearmetadatacache the same way. If custom fields still aren't showing correctly in Aurena after all of that, consult IFS's Aurena attribute-configuration troubleshooting documentation for further steps, since a persistent instance-wide symptom like this (versus a working sibling instance) usually points to one of these caches being specifically out of sync.
