wipe wall

Does the wipe wall only happen in certain circumstances?

I am trying to get it to be propagated during the support and no setting I make will make it show?

Only when some type of dual extrusion.
If you are using same material support- that does not use a wipe wall.

The whole reason the wipe wall exists is that the nozzles move together and so the unused nozzle at the time may ooze and when it does, it's also potentially crossing over the printed object layer while the other nozzle is printing. The idea is that the wipe wall catches this ooze, and then also is a structure so that repriming that other nozzle when required for the layer has a structure not on the print to catch up for the lost ooze. Just trying to explain, the ooze wall has a lot of purpose and is sued for a lot of reasons to solve issues of typical dual extrusion.

Here is why you may no see a wipe wall.
The first general rule is left nozzle is primary and thus the general default.
If and when you turn on support from the simple menu (not showing the advanced full profile) support is also defaulting to the left nozzle and thus "same material support". Just means the support structure is the same plastic as the actual print.
Again, at this menu, what you do not see is by default, and only seen in the advance menu is that the support extruder defaults to left and that being the same default extruder for the object is "same support material".

ONLY if you assign the support to the OTHER extruder (Right), then you are invoking dual extrusion and thus alternate material support where one plastic is the model the other is printed for the support structure.
You also have options from what i'm seeing, to say potentially make the tower structure of support same material, and then only use the other material (say some form of soluble or other support material) for the dense layers right before the actual object overhang layer.
