There are missing points in the consecutive numbers in the list of open points (LOP)!

One possible explanation for this is that “irrelevant nodes” have been hidden. This also hides all open points assigned to the node that has been set to irrelevant.

Click on the “View” tab, where the “Hide irrelevant nodes” option should be activated. Uncheck this option by clicking on it again - now all nodes and thus all open points will be displayed again.
