Do you create a Model-Driven app based on your D365 CRM Entity?
Could you pleas share a screenshot about your issue?
Based on the issue that you mentioned, I have made a test, and the issue is confirmed on my side. For your first question, as an fixed solution, please consider use the following formula to submit your form data instead of the the ModelDrivenIntegration.SaveForm() formula:
For your second question, it is a normal behaviour. In default, when you execute the ModelDrivenIntegration.OpenQuickCreateForm(entityName) formula, it would open your Quick Create Form rather than docked to the side.
I would also post this issue to my product team, if the issue is solved, I would reply here.
