The warning message in orange suggests considering disabling “use multi-MPPT feature” for ensuring power sharing on each input. With all the strings being the same there is no need to activate the multi-MPPT feature and in Case 1 you risk getting overload losses if you do not define a set of subarrays where each subarray has a number of strings that is a multiple of the number of MPPTs. By activating the Power sharing and ticking the box "Auto-equal. Pnom" you should arrive at similar results as in Case -1 and the "single-line diagram" button will be activated.
