IfcTester - applicability bug?

Hi, have a problem with the applicability of my IDS in regards to IsExternal in Pset_WallCommon.
If I use this IDS that hast two specifications each with am applicability of the name "Ortbetonwand" and one with "IsExternal=TRUE" and the other with "IsExternal=FALSE", Bonsai does apply both specifications only to objects with "IsExternal=TRUE". Solibri does apply these correctly with the same IDS so I assume its a Bonsai/IfcTester-bug.
Tested with 0.8.0 in Bonsai and ifcOpenShell Command line.
Is it just me that has this problem? it seems to basic to be a "regular" bug.
i would really like to use Bonsai for my IDS-reports, as I have to do a lot of them for a big project.
