1967 Electric headlight door conversion stuck open

Randomly today, the headlight doors have decided to stay open after turning off the headlights. Conversion is two years old… The newer version from WCCC. Before I start tearing things apart, anyone have a similar issue?

One troubleshooting process I did was disconnect the battery and reconnect. The doors closed. Turn the headlights back on, doors open. Turn them off, they stay open.
