I too am having problems with the FBS system in the Stagescape. It does'nt seem to be cutting any of the feedback especially in the monitors where I need it to work the most. What's up with this issue?
Feedback Reduction Barely Working

You wouldn't be able to actually "hear" it set any filters. They are too narrow for human hearing to detect.
Feedback management is set on the input page in deep tweak. It is automatically assigned to those inputs that typically have problems but not set to all presets (e.g. electric guitar settings). You want to use it in the universal setting if you are running any music through the mixer.
I would suggest as a start you make certain that your mixer is running the most current version of the firmware. It is available on the downloads tab from the main Line 6 page. Secondly create a new setup just in case somehow a switch was set in the wrong place. Try a test with a single mic (vocal preset). Switch to the input tab while in deep tweak and you should be able to see it set filters as you bring the system up into feedback.
That said, there is a limit to how much it can do and feedback will occur with all systems. This will depend on your exact system, its layout and the acoustic space you are trying to work in. Typically you can expect 3 to 12 dB improvement in gain before feedback.
If you are also using Line 6 speakers I would recommend shutting the Feedback switches to off and let the mixer do the work.

As Don points out you need to use less aggressive FBS settings for instruments (universal) or you'll get some weird side effects happening. For the acoustic guitar issue I would try using the PARA EQ to try to tame it... They tend to be too boomy anyway on he lower strings. Depending on what notes are actually feeding back either notch them (likely somewhere between 185 and 220hz) or even try a gentle shelf EQ from 220hz down and lower the whol range til you get a nice even sound, which should help deal with the feedback as well.
