KOSMO 1222 Tuner VCO Build Series

I’m wondering if anyone can enlighten me to what i’m doing stupidly. I build 2 of the stand alone tuners now. One rack mount, one not. The display i’m using isn’t the same one as the stripboard, but does have the exact same pinout. They work, but the display is all jumbled. Any ideas? Where would I start to troubleshoot this?

This is the display I have… 5161AS
