Forms integrating with CRM Mapping dependencies

Forms integrating with CRM Mapping dependencies

Hi Team,

Please help me out in this. I have integrated zoho forms with zoho  CRM.  In form i have a dropdown  of AREA list,  in CRM dropdown "area field " is mapped as dependencies with Region field.
So now the problem is when Area is selected in form and on submitting form, the data is getting into the lead i.e area to area, but region is not getting selected automatically, as i have mapped dependencies area with region. in this case I have to open the lead once and need to click on area field once then region dependency will get selected. 

Can you please help me how i can resolve this or does zoho has limitation ?
