I am making a small multiples visualization of about 32 different maps, all from the same shapefile/source using QGIS 3.0.1. I am using the "Provide feature filter" to select the data that I need to display.
I update each map, one at a time, but when I zoom out using my mouse, it completely erases all the work I've done and changed every single map to my most recent filter selection.
Prior to zoom:
This is what it all changes to as soon as I zoom out:
In some of the maps, as soon as I zoom out, they lose the ability to "lock layers."
I tried "lock layers" as well as "lock layers" and "lock styles for layers." I've tried using the same CRS for every map as well as selecting "draw map canvas items."
I am at a complete loss.
