qgis - Select by location is not working in the processing modeler

When I run the modeler in qgis 2.14 I get no results from the select by location algorithm. I tried outputting my buffer polygon and using the select by location plugin and it worked fine. I have the same setting in both but for some reason the modeler doesn't do anything.

Answer

After trial and error I found that adding all the parent algorithms makes the select by location work.
