SEFx 3- Can't turn off border from preset

I have noticed what seems to be a new issue.
When I use a preset which applies a border, often I like to remove the border but retain the other settings specific to the preset…
I am finding that that border which was applied by the preset seems “sticky”.
That is, after using the border selection drop-down and selecting “Off”, as soon as my cursor leaves the box the previous border re-applies. Repeatedly.
This occurs whether silver Efex is accessed through Photoshop or Lightroom.

Tried this from PL4 (supporting SEP3) … and no, no problem to only set back the border (off / change to another type), and also no problem from a already rendered TIFF-file when reopened in SEP3.
