Trying to display past value.

[slo]

Noob here trying to come up with a scheme to display past values alongside current active values from an encoder.
The code below demonstrates the problem I'm having. Setting encoder 1 in bank 2 and then switching back between banks produces the desired result, but in bank 1 it looks like the past value is getting over written so encoder 1 bank 1 is not displayed. Using a SSD 1306 display. Below is the .ngc ,ngr .ngl
I need a better scheme or hints to the path forward. Thanks.
