AME CC renders AE projects progressive (not interlaced)

Hi folks,

we updated to CC 2014.2 last week and are now stuck without fields - and as a broadcaster broadcasting 1080i we desperately need interlaced files!

Here´s the detail:

For a quick demonstation I created a simple AE project (CS6) with a blue bar rotating around the center.

This same composition is opened in AME CS6 and in AME 2014.2 and rendered with the identical settings:

This is the result from AME CS6:

This is the result from AME CC 2014.2

During the last week we tried everything to convince AME 2014.2 to render in fields - but we didn´t succeed...

The only workaround is:

Then AME renders it interlaced...

Please note

I´m not talking about interlaced or progressive videomaterial but about the field handling of AE animations itself in AME
under "Quelle/Source" it says "progressive", but you can´t change the interpretation on a AE composition
in AME CS6 it says "progressive" as well but renders out fields
we tried this with several different projects and compositions on different computers (PC and Mac)
scary: identical sources with identical render settings produce different files in AME CS6 vs. AME 2014.2
it´s not just the field/progressive thing - mp4 files from AME 2014.2 are half size than from AME CS6

Thanks for your help - we really need our fields back... ;-)
