More of an "annoyance" than a bug, but..

Running AA 13.0.11.38 under Win 10, 2004.

I have met this "annoyance/bug" several times recently and wanted to post about it, primarily to discover whether anyone else is seeing the same thing, whether it can be "corrected" or whether it is simply down to user-error.

Working in Multitrack mode, various clips on different tracks, some effects applied, via the Effects Rack, either to individual clips or sometimes to whole tracks.  Saving and closing the session, no problem.  However, on re-opening the session, perhaps some days later, all effects still listed in the Effects Rack but the rack's input and output meters show no activity during playback.  The effects are being applied (clicking on the bypass button on any single effect or the whole rack the "change" is clealry audible) but the meters do not move.  Sometimes, clicking on the Effect name in the rack will "wake up" the meters; other times they only activate if at least one of the selected effects is "edited", even if no actual change is made.

Anyone else seeing this, or knows why and/or how to avoid, or is this user-error or even user-ignorance?

TIA for any advice.
