OMASA rendering to MASA 1TC makes objects on the right side disappear.

When rendering e.g. the following OMASA scene to MASA 1TC, any object on the right side either disappears totally or gets faint when the resulting audio is listened.

OMASA_Cat6_S1.zip

Here are the command lines to reproduce the problem with MASA 1TC output, latter speech objects disappear totally:

ivas_rend -if ISM3MASA2 -im Nokia_Cat6_3ISM_S1.o1.csv Nokia_Cat6_3ISM_S1.o2.csv Nokia_Cat6_3ISM_S1.o3.csv Nokia_Cat6_3ISM_S1.met -i Nokia_Cat6_3ISM_S1.wav -of MASA1 -o P800_Cat6_S1_MASA1.wav
ivas_rend -if MASA1 -im P800_Cat6_S1_MASA1.wav.met -i P800_Cat6_S1_MASA1.wav -of BINAURAL -o P800_Cat6_S1_MASA1.bin.wav

Using MASA 2TC has no problems, all objects can be heard in the correct directions:

ivas_rend -if ISM3MASA2 -im Nokia_Cat6_3ISM_S1.o1.csv Nokia_Cat6_3ISM_S1.o2.csv Nokia_Cat6_3ISM_S1.o3.csv Nokia_Cat6_3ISM_S1.met -i Nokia_Cat6_3ISM_S1.wav -of MASA2 -o P800_Cat6_S1_MASA2.wav
ivas_rend -if MASA2 -im P800_Cat6_S1_MASA2.wav.met -i P800_Cat6_S1_MASA2.wav -of BINAURAL -o P800_Cat6_S1_MASA2.bin.wav

Here is a Figure that shows how the two latter speech objects are missing from the audio rendered from the MASA 1TC (upper), where as they appear correctly in the MASA 2TC (lower).
