Receive EQ Flat on Other than Slice A

I noticed something quirky with the receive EQ today.  Not sure if this has been posted before.  I believe it is new with 3.1.8.  I’m running a 6600 at 3.1.8 with Win 10 i7 laptop.

SSDR opens with a single slice and the receive EQ is applied as expected.  When adding a second or subsequent slice to the same panadapter, the receive EQ is not applied to Slice B, C, or D until I toggle the mode, i.e., select CW and then return to LSB or USB.  The EQ octave sliders do not change position and remain at their at the expected EQ settings.  If I open Slice B on a second panadapter, the receive EQ is applied without toggling the mode.

I tried a factory reset and cold reboot with no change.  After the factory reset, I tested before reloading my profiles just to be sure there was nothing odd in my profiles.  Another benign observation is when exiting SSDR, the last half-second or so of audio sounds as if the receive EQ is turned off and seems to have a flat response.  Has anyone else noticed these quirks?
