No idea why the change is not being reported - software error or someone not setting a flag?”
Interesting point that you observe that it is still transmitting on the original frequency. I wonder if what we are seeing is the result of channel moves following a procedure of some sort of rolling, overlapping change, to avoid interruption of output - particularly for anyone with manually tuned receivers.
Picture this sequence:
1) You start broadcasting the same channel on another frequency, the intention being that you are going to allow people manual or automatic retune time. You may even put a caption on the video due to be turned off. Some boxes will say that a channel has been added. Users will examine the lists and say "I can't see anything new". Some boxes may decide not to say anything because no new user-facing channel has been added. Internally they may have kept the original transponder details or used the new ones, it may depend on a scanned order. If it is a Freesat box it is hopefully getting told via the EPG, but for all I know the EPG may only specify the logical channels, not where to find them.
2) A day later you turn off the old service. Could the box call this a deletion? No user-facing channel has been deleted. Maybe this could be an update, if the box had needed to switch to the new frequency. If the box was already using the newer frequency then there hasn't really been an updated channel. You could argue that there has been a disturbance in the Astra firmament and call that an "update" I suppose.
This is just my speculation. Maybe someone knows whether the hypothesis fits the facts as well as the observations
So in the end we see multiple rescans because there are frequency shufflings going on. Hopefully it is to fit more stuff in, or group channels better so people with a single cable can receive more channels at the same time. I just hope it is something to benefit us consumers of
Freesat.
