Weird Problem with DVB-S2/Spiderbox/Dragon-T-Rex CAMs

eg:

FX & Fox Life Greece @ Eutelsat 12 West A (12.5°W)

11181V (DVB-S2 8PSK) SR 22400 FEC 2/3
11428H (DVB-S2 8PSK) SR 30000 FEC 3/4

on both freq's FX Greece has the same SID: 0712 (DEC) / 02C8 (HEX)
and on both freq's FX Greece has the same VideoPID: 7121 (DEC) / 1BD1 (HEX)

on both freq's Fox Life has the same SID: 0711 (DEC) / 02C7 (HEX)
and on both freq's Fox Life has the same VideoPID: 7111 (DEC) / 1BC7 (HEX)

So a Predator file patched with the current keys and Biss CaID 2600, SID & VPID should open both Fox Life's and both FX Greece's

But for me with Spiderbox and Dragon/T-Rex CAM with Predator file only the 11181V transmissions open.

Its definately the same key/s for both freq's as with Diablo CAM (which only uses SIDs) all 4 channels (FX x2, Fox Life x2) open. And if the keys and freq's are entered directly into the Spiderbox UCAS all open fine.

I have the same issue with the 11387V channels on 10°E (PLTV, NBA, Chelsea TV all fine on Diablo/Spiderbox UCAS but no longer work for me with Dragon/T-Rex & Spiderbox)

What could be the problem with the older Dragon/T-Rex CAMs?

1) A DVB-S2 issue with these CAMs?

or

2) Compatibility issues with the Spiderbox?

or ???
