I'm configuring a custom format for a SQL datasource using Telerik (desktop) Report Designer v18.104.22.168.
I create the custom format for a date field as such
I click OK and when I preview the report I get an error "Input string was not in a correct format". Looking at the custom format settings again, the value type changes back to numeric as below
Why does the Value Type change back to Numeric?
A similar issue occurs with CallTime when I format it as HH:mm
The property for the fields do contain the appropriate format values
