BOS Tasks + Fysical button

Hello,
I have made a task that opens or closes all my blinds.
There are 2 blinds in a corner that interfere with each other. So I've put a block the actuator that doesn't allow the 2 blinds to move together.
It's been working perfectly for over a year now. I've been activating the task on the visualisation until now.
They all move together, but 1 of the 2 in the corner stays stationairy until the other one is fully opened or closed. Then the last one does it's thing.
Now I've programmed a fysical button to trigger the task but it's got an issue.
The blind that waits til the other one has finished, doesn't close all the way. It stops at half the length it should travel. When i look in the visualisation, it thinks it's fully opend or closed.
I don't understand why it does this when triggered on a fysical button, but doesn't when i trigger it on the visualisation. It's the same task
It almost looks like the time it is waiting in blocked mode, doesn't get added up after. But all this logic should be executed on the KNX actuators rather then the BOS?

Hey
How did you program the physical button in KNX? So it now ignores the bOS scene? If it works correctly with bOS trigger then why not link it to the physical button to trigger the scenes?
