Irregularities in terms of temp folder recognition for new sites from HUB to SPOKE

I started to try the HUB and SPOKE Model - whereby I would initiate sites on the HUB - to be synced to the SPOKE. Now there is one thing that seems a bit odd: The temp directory is never recognised correctly. So many of the installations do not work correctly.

Everything is fine after going to file systems page and saving one time. The entry on this page is actually correct.

Any thoughts? Never had this? on a single server aegis instance.
