Problem with visibility buttons in interactive pdf

Hi,

I have created an InDesign document with three columns. In column 1 are 4 regions, North, South, West and East. In column 2 are the corresponding suppliers of each region and in column 3 are the contact details of each supplier with hyperlinks.
In column 1 and 2, all regions and text boxes are converted into buttons. These buttons have the property of making the other buttons visible or invisible.
When opening the pdf, only column 1 is visible. For example, if you click on region North then the corresponding suppliers will be visible in column 2 and if you click on one of the suppliers then its contact information will be visible in column 3.
If you then click on another region then the data in columns 2 and 3 should become invisible. That is where it goes wrong, in column 3 the contact data remains visible while it is set to invisible.
I have already saved the document as .idml and reopened it but that does not help.
Attached are some screenshots for clarification, the InDesign document and the interactive pdf.
The document has also been published online, it can be viewed at https://indd.adobe.com/view/63270167-354b-425b-8f62-08c7a97c1f0d
Online everything works fine.
