Automatic formulas in schema regeneration

I have an application with an Appsheet database, which when I regenerate the structure of the main table, automatically fills in all the initial values ​​of the DateTime type columns, causing me to review and delete those formulas. If I am not aware of this behavior, it can cause problems in my processes. Can these automatic fillings be disabled?

Thank you very much!

AppSheet Database has many flaws. I recommend against using it. I use Google Sheets with great success.
