One of my IOK files is not loading a new field introduced to it by in-file read blocks (loading in IOK's), nor is it dropping a field that has been deleted from those same source blocks. It is behaving as if it hasn't cached out, keeping memory of the old menu of fields. Previews in operation blocks upstream from the final blue Omniscope box show the new field as present and the deleted field fully removed, yet the final dataset isn't refreshing to reflect this new reality.
