non-destructive filter not OK?

[Dsbbw2020]

Hello,

Description of the problem:

I want to use the recipe for "Freaky Details" (https://www.gimp-forum.net/Thread-Look-m...-Gimp-2-10), That is:

 - Make two copies of your original image (three layers total)
 - Color>Invert the top layer
 - Filters>Blur>Selective Gaussian blur the top layer (radius around 5 px, max delta around 0.2)
 - Add a layer group at the top, and move the top two layers in it
 - Set the color-inverted layer to Vivid light mode
 - Set the layer group to Overlay mode

If I do so in Gimp3.0 RC1 everything is OK

Next I change the original image with the function: color -> exposure (+ or - , both tested)
After applying the recipe the result is now unexpected. Sie screen1.jpg.

If I remove the non-destructive filter (exposure) from the top image (the inverted one) everything is OK.
