TS2 Digital Framing Matting Fault?

I used the White Matt preset, and attempted to adjust Image Shadow Strength:

it seems to be an either/or situation: ON or OFF? I’m hoping that this is a glitch,
and the the full gamut of shadown and contrast can be under slider control?


Not seeing that here Jack on Windows 10 Pro and Studio 2 v2.0.11. The screen shots below are using the White Matt preset with various values of Image Shadow Strength.

Image shadow size was constant at 0.26 and Image Shadow Diffusion at 0.87 for the above image set
Progression of Image Shadow Strength from 0.01 up to 1.00 using a mouse on the slider, or by selecting the value box and using the up/down arrows is quite smooth.

I agree with Greyfox, OK for me on Win 10 also.
