I’m having trouble creating a data type from a folder (or even a selection) of OPC tags. The dialog that appears only has one tag in the data type structure. I don’t know if there is something about the OPC tag that is causing this. I’m not seeing this behavior elsewhere in the tag tree.

I attached a screenshot of the behavior I am seeing. I also attached a screenshot showing the configuration of one of the tags. The rest are similar, only changing in address, except for the boolean. That is a HRxxx.x address.

Edit: I’m currently running 7.8.2.
