I have a object WSA having lookup relation with contact. Created a flow to insert record in WSA. 
Now I am trying to update contact with inserted fields data of WSA to Contact. All fields are getting copied. BUT
The marital\_status\_\_c(Picklist) field of WSA is NOT populating or copied to MArital\_status\_\_c (Picklist) field of contact. Its coming blank.

Is the issue related to picklist? How to solve the issue?
