[Bug] Encoder retains base layer behavior on another layer

Describe the Bug

I'm not sure if this is a bug. I'm setting up encoder behavior and have the following keymap.c

The encoders should do PGUP/DN and VOLU/D on the base layer, but Left/Right and RBG adjustments on layer 1. They continue to do PGUP/DN and VOLU/D even with MO(1) held.

I'm wondering if this is a bug, or my misunderstanding of how MO(1) should interplay with the behavior? I'm also new to QMK and have stuck with "regular" numbered layers vs. reference I find use _RAISE/_LOWER, so it's hard to find a good apples to apples reference. I interpreted the docs to be an either/or situation (use encoder_enable or encoder_map_enable) because the Keebio docs say so. If parameters from both sections are needed, I'm likely missing a lot of configuration params.

My rules.mk purely contains ENCODER_MAP_ENABLE = yes.
