I think you need a A2 lite version to get it running smoothly. I run 2 lite models in parallel with added effects like in your second screenshot.
Do they have a portal/account you can log in? perhaps you can download newer versions because often NAM profile suppliers offer re-learned models for free after purchase.
I tried to figure out, diging thorugh the model file how te determine the difference but I couldn’t find something that gives you a hard yes or no on A1/A2.
By my knowledge there is no way to just convert A1 into A2 withou proper re-learning; something the supplier should do.
bottom line: They should get back to you with a proper answer 
Side note:
Keep in mind though, as soon as you reboot the Dwarf, it will jump to full model; even though you saved the preset as lite.
that bug is logged here but never asnwered so far…
