I regularly use PHD2 for guiding, and it works nicely together with Ekos. However, recently the guide image pops up in the Fits viewer, despite using PHD2.

Is there some setting that I might need to change, or what is happening?
Ekos Guide module used to disable this, but this was proven to be problematic and complex, so it was disabled. You can still do it manually via the INDI Control Panel. Go to your CCD driver, and under Image Info as illustrated below:
