Button does only work on preview mode

Design help General
1

Hi people,

i have two issues with a button i just can’t fix.
The Button opens a simple modal.
Therefore i created two interactions called “Popup Open” + “Popup Close”

Problem 1: The button is only working in preview mode.
I’ve already checked the interaction trigger, created new ones, but nothing helps. Also i can’t see any elements which seem to block the interaction.

Problem 2
On first view, it seems like everything is working in preview mode. When I click the button once, the modal opens. When i close the modal and want to reopen it by clicking the button again - nothing happens.

Can anybody help me to detect the issue?
many thanks!
