Hello once again.
I am experiencing an issue that seems to lie within the fault of how PowerApps reads/saves Data out of an Excel Sheet stored in OneDrive (related to checkboxes).
I use forms to create a set of data, checkboxes working as intended, saving a "true" or "false" value with the right data format (the TRUE/FALSE data format from Excel, I have double checked this).
The problem occures when trying to edit the data set I have just created. All values load in correctly, except the checkboxes, all of them appearing blank, giving me the error that they require a "true" or "false" value.

The value is actually saved as "true", however the data format is probably loaded in a text format, not allowing the checkbox to regain its original saved value.
Below is an example showing the checkbox being empty despite the checkbox and the textbox loading the same default value, it being set to true.


(Saving the edited forms now would set each Checkbox to false, as they are now unchecked)
I believe there is no real way of working around this issue. The Checkbox is required to keep its current default value in order to update the EditForm correctly. However the default value cannot be loaded, making me unable to ever edit the Forms I have created within PowerApps, leaving the app I have created useless.
I am open for suggestions and possible work arounds. I was unable to find anything related and would like to keep working with Checkboxes, possibly seeing this issue fixed altogether.
Thank you for your time.
