Required fields are missing error but they are available.

Izunna, do you have the fields checked as required from the Skuid page builder or from the Salesforce back end?

From the Salesforce Back end. But these fields all have values for them and are not missing but I get the error.

Izunna, the error disappearing when you click on it is just standard error behavior (it doesn’t mean that the errors are gone).

Do you have any record create actions running? It’s possible that there is another record being created in the background that is not being displayed, and so the errors being showed are related to that record. That’s one possibility. 

I looked through the actions for models to no avail. I decided to turn the Save/Cancel Button into two separate Buttons that did Save and Cancel respectively and I am no longer getting this error. I added the save/Cancel button at the side and the error came back again. There might be a bug here.
