The bounds for the Map View should automatically be coming from the Legend specified.
Which version of M.App Enterprise are you using?
Before saving the Map View for first time, if the Legend is specified the bounds should be blank and the astericks and 'this field is required' should be gone.
After the saving of Map View it can be edited and the exact values of bounds taken from the Legend will be shown.
If this isn't happening for you then it could be that the Legend is not valid or doesn't contain any layers. It should be examined the Legend contents.

You can upgrade to the latest M.App Enterprise version 2018 Update 3 to see if the issue gets resolved there. I dont recall this being an issue on your version though.
It should first be examined the 'Change_Detection' legend you are specifying for the Map View. Does it contain any layers? Please show screenshot of this legend.

Thank you for the screenshot of 'Change_Detection' legend. The issue is due to the legend having only images and no vector layers. In this way the bounds are not known automatically and should be done manually.
You may test another legend with some vector layers to see that bounds are created for Map View automatically in that case.
You may wish to add Product Idea for it to also be the case when using legend with only images.
