Error when using extender search relative years

Hi,
I’ve got an error
“RuntimeBinderException: Cannot implicitly convert type ‘string’ to ‘System.Collections.Generic.List<System.Collections.Generic.Dictionary<string,object>>’”
AspNetMaker2020.Models.project_name+_project_and_opportunity_SummaryBase.RenderRow() in project_and_opportunitysmry.cs
+
payment_date.EditValue = payment_date.FormatAdvancedFilters(payment_date.EditValue);
when using extended search, and choose Report settings->relative years

Is there any step that I miss?

Make sure that the field is enabled as a lookup field for itself (i.e. Use Lookup Table, Lookup table name = Report, Link field / Display field = Field).
