Field does not update SharePoint column with a value



I have a prod canvas app has been working for months. User reports they cannot approve a section as 1 of the fields cannot be written to - I've searched long and hard but could not see any reason why the field what appears to be in view mode - so as temp fix I hid that 'faulty' field and added the same field again on the screen.
User is now able to complete that section, but when I refer back to the submitted form, or SharePoint list item, there is no value in the new field I have added in the canvas app..... not sure what to look at I have looked at the following:


The Update property of the DataCard is correctly set to the field it contains:



Thee Items property of the field itself is correctly set to I have a date field which gets written to, but this field does not get written:


It is definitely submitting the form as I have a condition on the submit button where DataCardValue33 cannot be blank, but the data from this 1 field isnt being written.


My submit button has the following, so no patching taking place 



What else should I check, as I have not made any changes to this new data card, simply added it from the Field - Edit option as a work around, not proving to be very effective,

Hi @WarrenBelz 


Thanks for your input, I cannot test this, as the new (replacement) field I added to the screen after porting my question is playing up too and not editable either.
I have no choice but to restore the form to a previous version from about 2 weeks, there have been changes to it and I will need to make each change again 1 by 1, to see what breaks this field on this screen.
