Thank you for this example @kodi75, this issue is likely related to this bug report - it is currently being investigated. I will move some posts from here ro the linked thread to keep all relevant information in one place.
Now, that we’ve got more examples, I attempted to accept the previous suggestion you provided and it threw an error upon trying to save it with no changes made on my end. Since the issue is related to the address, I modified these fields - entered ‘None’ in the address and city fields, and it has been added successfully. Please let me know if you have further questions.
All the best,
Olesya
