How do I fill a single form two relational lookup fields data with select data?

Hi Zoho Community,
I have created a zoho creator form with two dropdown lookup fields and I have set the query to filter one lookup field's data based on another look field's input data. 

But When I have filled the lookup field value with selected data on form load time. But due to the query filter, one lookup field filled data automatically removed with a little bit of loading.

How can I solve this problem ???
