Tvheadend

No matter what I do, i tried troubleshooting with mpms @irc #hts, as soon as the mux 12129V get's scanned it get's a wrong TSID overwrite.
2017-10-24 23:19:51.637 tbl-base: pat: 12129V in Freesat: TSID change detected - old 07e6 (2022), new 083c (2108)
The old one 2022 is the correct one, and apparantly this is a strong factor in service mapping, because this mux with all the right parameters show all the wrong
services because it looks to its TSID. 2108 has a bunch of religious channels which are displayed upon tuning into it.
I 've deleted all muxes and just added the home mux of Tvheadend and it still happens.
I 've set in the tuner to skip the first x bytes, it still happens
I 've set the mux to ignore TSID, and to accept zero TSID etc, still happens.

My request is, to enable to edit the TSID when you manually add a MUX. The reason why this happens to my on my osmc, raspberry 1 with a Tevii 660 usb might never become clear
but being able to manually overwrite a TSID would be enough to fix this.
