Constantly Adjusting Z Height Offset

Good day! I am running a Klipperized Sovol SV06+ and have been getting some really great prints. I am however having an issue where lately I am having to adjust the Z offset with each new print. I did a first layer calibration and got a perfect result but after a couple prints I saw I needed to lower it to get a good first layer. Again I printed a few and then again I needed to lower it. This has happened a few times.

Yesterday I was printing a pretty large print and midway through the extruder shifted (the print remained secure to the bed) and continued printing. After I canceled the print I had to lower the Z offset much further than I thought was possible. I am concerned that the bed keeps "lowering".

I have a very good bed mesh loaded (used the silicone bed leveling mid I have seen discussed). I am just unsure why this is needing to be adjusted and why the last print went wonky (related?)

Thanks much!
