What am I not doing right?

For subwoofer graphs, please use the standard Vertical graph axis of (45dB - 105dB) and the Horizontal graph axis of (15Hz - 200Hz) using the Graph Limits button in the top right corner of REW.

Everything works fine until I enter filters into the FBQ

What method are you using to enter your filters?

Push the PEQ button
turned on channel ( have tried 1,2 ect and 19,20 ect)
Push FREQ button and adjust
Push GAIN button and adjust
Push BANDWIDTH button and adjust
Push PEQ button and run REW

Be sure all the filters in the channel are set to parametric.

Remove all the filters and then play a tone with REW's Signal Generator (i.e. 50Hz) and have the tone coming through your sub (low volume). Then play with a single filter at 50Hz on the FBQ while the tone is playing to see what happens......

Best to ask acoustic related questions in the acoustics section of the forum. They're more equipped there to follow up on your questions..
