And after giving "cs+ps" permission, when trying to set to "none" again,
I get:

@rafael2k, keith: are you running multiple SGSNs in the network? If so, then this is probably the cause:

https://git.osmocom.org/osmo-hlr/tree/src/db_hlr.c?id=28f0774e341c3dbe1045ca61a1dd3f1e903f55d0#n895

Right now we are telling all connected SGSNs to delete the subscriber data if the CS network access is removed for one subscriber. Instead of only telling it to the SGSN that the subscriber is actually using. Therefore the other SGSNs will report back to the HRL, that they can't delete subscriber data, and that is where the log entries come from.
