Deleting or avoiding Null values and Empty strings

I checked the settings of the "Is Null or Empty String" validation function.
Those settings are matching the screenshot provided to me yesterday.

On the screenshot you provided I cannot see the object name
Is Nul...

If you are using Is Null validation function please make sure the settings are the same as well

If it is not not working please post more screenshots

It must be done for all fields

I can see from the log that most of the errors are related to F13 F2 and F14 fields
