Radio Recordings have zero filesize

[SkyFan]

The only things recording at 12am-12pm on Mar 24 were 5 radio stations. The “BBC WS” and “LBC” radio channels recorded fine. However the file size for the following channels is zero:

20210324 0000 - BBC R2 - xRadiox - BBC R2 (Daily) 12am-12_05pm.ts
20210324 0000 - BBC R1X - xRadiox - BBC R1X (Daily) 12am-12'05pm.ts
20210324 0000 - BBC R1 - xRadiox - BBC R1 (Daily) 12am-12'05pm.ts

I don’t know why that is. They were recording fine for weeks. I have 2 twin FBC Tuners connected to a standard LNB. Setup like this so there's no reason why the box should have trouble recording 5 radio stations at once:

Tuner A: Vuplus DVB-S NIM(45308X FBC) (DVB S2X)

I then tried to record several other radio stations about one hour later than the above start times and they all had a file size larger than zero. So it seems there was nothing stopping any radio stations from being recorded so any idea why the above stations had a zero file size?

I looked at one of the timers that had a zero file size and it said this:

61806
