Load Disappears at CL of Bearing

I'm fairly new to PGSuper, and I've come across an odd problem. Within intermediate spans, user input loads seem to disappear at the centerline of bearing. As you can see from the attached pdf, I start a 4.1 ft (for some reason that is beyond me, the load looks like it is over the centerline of bearing). As I get closer to the CL of bearing the load seems to just disappear and reaches 0 at the CL of bearing. I would prefer to not have to manually find the location where one bearing takes all the load each time.

Is this a known problem? Or do I have a setting messed up somewhere?

Any help is greatly appreciated.

Not sure what you are describing. Provide your PGSuper input file and specific steps to reproduce the results you are referring to.

If I add a user defined load

If I add a user defined load of 100 kips at a location of 0 feet, checking the Bearing Design Parameter Report, it shows the Girder Bearing Reactions due to User Defined Loads in Interval 19: Open to Traffic at Pier 2-Ahead as 0 kips. If I move the load out to 0.1 feet, checking the same report the reaction goes up to 18.71 kips. Continuing out to 1.54ft (end distance and bearing offset different from original post) the reaction goes up to 100 kips. If I change the end distance and bearing offset, then the distance at which the reaction equals the defined load changes as well. Only in the intermediate span though.

The .pgs is uploaded as well.

I posted an explanation right

I posted an explanation right after your question - don't know what happened.

The point load input window is mis-labeled. The load for the intermediate span is between CL Piers.

I've logged this as an issue and will revise this capability so the UI is accurate and the loading input is intuitive.
