No Infill For Small Objects

I am unable to get my RepRap to properly perform the infill on small objects. Even though the objects are solid in the CAD models and the infill is set to 100%, small shapes come out hollow. I've attached photos of a test piece I've been working with in an attempt to correct the problem. The piece includes a 2.5mm, 5mm, and 10mm diameter cylinder. I have a 0.35mm hot end. My gcode is generated by slic3r. The object in the center of the photos is the current "baseline" configuration for my printer. The object on the left is the result of changing the extrusion multiplier from 1 to 1.3. The object on the right was made by increasing the number of perimeters from 3 to 6.

Increasing the extrusion multiplier did not fix the infill problem and made for a very messy print. Adding more perimeters made the 2.5mm and 5mm cylinders solid, but caused the 10mm cylinder to require less infill and become hollow. Can anyone offer advice to make the infill work properly?

Edit:
Posted the photos I forgot originally.

what speed are you printing the infill

My current infill speed settings:

Infill: 60 mm/s
solid infill: 60 mm/s
Top solid infill: 50 mm/s

I tried slowing the printer down, but if it did result in any improvement it was minor.

Sounds like the slicer could be acting up. Try using another slicer, probably Kisslicer or Cura.

How's the filament coming of the spool if it catches it will pull on the extruder what percentage of infil set in your slicer

I'll have to try that. I have an old version of Slic3r, so I'll try downloading the newest version of that first.

I don't think the filament is catching because the parts that don't get filled are missing material consistently, rather than sporadically losing sections.
The objects are solid in the CAD models and the infill is set to 100%.

I started using the most recent version of Slic3r and there was an improvement in the infill on this object. Now I just need to get it calibrated properly. Thanks.

Slic3r has a checkbox "Only infill when needed." Make sure that is not checked if you want the object always filled. Sorry if this is obvious.
