I can reproduce this. As you said, it has certainly something to do with
the Pdos contained in the Xml file. For slaves with dynamic Pdos, the
simplest solution is to generate an Xml file with

ethercat xml -p<SlavePos>

and modify the list of Pdos to your needs. Then you can use the
'generic slave' block. If this works, you can switch to an own block
configuration.

The Moog block was implemented for the prior EtherLab interface, it
won't work with the new version.
