Export to excel at Expression backed record not working with multiple user filters.

Hi All,

we have expression backed record with multiple user filters. Record list is filtering with userfilters working as expected. where as when we click on the Export to Excel we are ending up with 

"At function a!queryEntity: cannot apply a filter with blank field name. please contact a system administrator for additional details" in exported excel sheet.

At List level filters are working as expected. Export to excel is not working. when we choose only single user filter that time export to excel i working fine. only issue coming when we select the multiple filters.

we are passing the filters using rsp!filters to list view expression rule as a parameter of type anyType.

Please let us know is it a known issue or any workaround to proceed.

Thanks in advance.
