3xDVB-T2, C-receiver doesn't work

[d2mac]

I replaced one Sat to DVB-T2 (now totally 3) but it doesn't work.
The new receiver works on the A & B slots but not on the furthermost one. Not even using just the one receiver work on that slot

When A&B are reserved and C would be needed I'll get error:
No data on transponder Timeout reading PAT

Neither the Manual tuning finds any channels with the C-receiver but for the A&B they are found OK.

The Sat-receiver worked on the C-slot, the new T2 receiver works on the other slots, I've checked the antenna as well.

I'm using the OpenVIX 152. What might be the problem, please?

FYI, seems that with the old Apollo 003 the turners are working but not later ones.
The latest Egami FWs are working.

Wondering if in some phase the old drivers are embeded in...

Seems that in v161 3xT2 receivers works
