The clock display does not light up the "1" for times 10:00, 11:00 or 12:00. It only displays the last 3 digits. Any suggestions ?

I have an Electrolux Gas Oven M# EI30GS55JS – and the clock display does not light up the “1” for times 10:00, 11:00 or 12:00. It only displays the last 3 digits. example is the display looks like 1:00 when it should be 11:00.
The parts diagram shows a glass cover and a separate control board. All functions for the oven work fine. I think I need to order the glass cover(part#318923502) or the control board (part# 316576703)?
