Hi@Zhangcy,
Based on the issue that you mentioned, do you want to bind the Update property with your data card?
Could you please share a bit more about the scenario, is it a custom card with your Form?
If it is a custom card, it makes sense. This is a known issue that a custom card does not have the property of Default and Update.
In general, the fields that we could add directly are the existing fields from the data source. Of course, these existing fields have the Update and Default property within the corresponding data cards.
Please check if you have added the correct fields from the data source, try to avoid adding custom cards. Further, check the data source you connected to see if this is the one you want to connect.
As an alternative solution, if you want to bind the custom data card to a specific field in your SP list, you could consider enable the corresponding field data card within your Edit form, then made some changes to it. Just to remove the originally predefined control and then unlock it to add whatever you want.
So far, a custom card could not have the property of Default and Update.
If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Forum:

Besides, if you insist on this card, you could consider using the Patch() function to save your data instead of the SubmitForm() function. Based on the screenshot, I assume that you want to save the date value, you can try the following Patch():
Patch(
test0917,
LookUp(
test0917,
ID = xxx
),
{
Title: "1010",
'test1': Text(
DatePicker1.SelectedDate,
DateTimeFormat.ShortDate
)
}
)
Best Regards,
Qi
