desktop policy setting document > preferences > replication
high priority is enabled but an option for replication interval is not shown.
enabling normal priority replication shows the replication interval (repeat every) option for both high and normal
can you just remove the hide-when formulae from those fields all together - or hide all fields for each type unless selected instead (preferably the former)
also the inherit option for each “line” should be the first field after the description, and if enabled should hide the remaining choices for that “line” to make it much more obvious as to which values are in use from this policy setting.
