error removing four pipe active beams in os v26 and v27

edit

I'm trying to remove some four pipe active beams in openstudio v2.6 and have the following issues:

1). when i try to remove directly in openstudio by clicking the x button for the beam object at zone level, the program gives this error "unhandled exception" error.

2). when i try to remove it via openstudio measure, using equipment.remove. The program throws the following advanced output for the error:

3). when i use the "enable ideal air loads for all zones" measure, it also throws this unhandled exception

Anyone knows what might cause this error? Same happens in OpenStudio v2.7.
