Bug? "Raster to Polygon" and "Extract Value to Point", Automatically add extension name, interrupt the procedure running.

[GuohanZhao]

Dear All:

Recently, I spot a quite tiny error in ArcGIS 10.4.1 model builder. So far, I found two tools have this kind of error: “ raster to polygon” and “extract value to point”. The error is that the tool will automatically change the output name after running it first time. it will automatically add a “.shp” extension. As the result, the whole process will be interrupted by this because my output work space is gdb file. So the output cannot write into the workspace when I run it for the second time, until I manually delete the file extension name.
