V12.1.8 "Depends On" Condition Not Working

Hi everyone, as shown below, I created a custom field named “Quotation Required Date” in Issue Doctype via Customize Form with “Depends On” eval:doc.issue_type=='Request for Quotation'. But it didn’t work like it is supposed to; as you can see in the second screenshot, the “Quotation Required Date” field did not appear when “Request for Quotation” Issue Type was selected.
