Help with Cura not loading stl model

Have a Monoprice Mini and using Cura 15.04.2 Not an experienced user, but have a couple dozen prints under my belt.
First print of a two part project printed fine. Loaded the 2nd .stl file and Cura loads the object on the platform, but does not update the print time and filament usage. Saved the gcode, but it is the same as the first print. Reopened Cura and loaded 2nd file, but still no print information. No problem comments on the Thingaverse project. Any ideas?

I have used Cura 15.04.6 forever and have never had a problem,
Though to get better prints I now use Prusaslicer mostly newest version though all work fine for me.

If you post STL files will look to see if the STL file has problems.
