I am running into an issue where some fields are being cut off when my PowerApp loads. It seems to be on the first initial loading of the PowerApp and only seems to happen to two fields but it is very inconsistent. The current workaround is to just refresh the page and everything usually works fine. I am not using auto-height/width. Below is an example of "Request Type" not showing the input box and near the bottom the "When to Send Out the Document" field is cut off.
Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned.
Please consider turn on the "Auto Height" property for the "When to Send Out the Document" field Data card Key (the issue is related to) within your Edit form (SharePointForm1), then re-publish your app, then check if the issue is solved.
If the issue still exists, please consider turn off the "Improved app rendering (final validation)" option within Advanced settings of App settings of your app, then re-publish your app, check if the issue is fixed.
