SCXI 1520 should be placed in the first SCXI slot while using it in a multi SCXI module setup.
Just put SCXI 1520 in first SCXI slot and put SCXI 1140 in slots after SCXI 1520 ( this order can be interchanged since both these modules are SSH enabled)
But always insert 1102 and1163 modules after these two modules( in the last, since both do not have SSH enabling)
this should solve your problem

Thank you for the advise,
We have not tested it but we got the advise to slow down the AI conversion rate manually with a property node and that fixed the problem!
DAQmx automatically sets the conversion rate to max (to match 333 ks/s) when it finds a 1520 card and that might leed to crosstalk between some other channels which was exactly what we got. We dropped AI conversion rate to 100 kHz in our 48 KS/s environment
