How to remove ambiguous date from the input tool?

I need to develop this alteryx condition at mapping dataflow level in adf. I tried by using filter tool to implement this implemented filter tool .

but when i am performing union tool with this filter tool and with another tool.

getting the error like this at union level.

here the column format is yyyy-mm-dd

I need the correct solution for this issue and how can i implement this alteryx condition in adf at mapping dataflow level can you suggest.

1.there is no column with the same name in filteringonDateBetweenDRO2! 2.the output of the filteringonDateBetweenDRO2 DatebetweenDRO. 3. the union settings is unionsettings.
