I am using OpenBuildings Designer CE update 5 (10.05.00.49), but I have also confirmed the below problem in the latest version.
When applying structural rules to plan views I always have Delta TOS set as one of the attributes all the applied rules.
I also ensure that when DTOS equals 0 that it is set to "Hide labels when delta = 0" in the view presentation options.
I am finding that this is not working as shown in the plan below:
It can be seen that there are a couple of variations in the DTOS display - one with brackets and one without.
I tried both options when setting up the rules but neither vanishes.
I should not see any form of DTOS where 0 appears.
Is this a bug?
