Metronic 8 asp .Net Core Modal Pop UP Not Displaying Properly

I must be missing some setup in scripts arrangements. I just use the starter kit of Metronic 8 asp .Net Core.

[HttpGet]
public IActionResult UpsertModal2()
    {
                ImageVM imageVM = new();
                //do something here
            return PartialView(imageVM);
                // return View(_theme.getModalView("Partials", "UpsertModal2.cshtml"), model);
    }

• return PartialView(imageVM);
• return PartialView(_theme.getModalView("Partials", "UpsertModal2.cshtml"), model);
  • both of this shows the form but not loading the Layout I think

I added new function getModalView to accept file from other folder: public string getModalView(string folder, string file) { return $"~/Views/Partials/Modals/{folder}/{file}"; }

I also include this in _Modals.cshtml: <partial name="~/Views/Image/UpsertModal2.cshtml" /> <partial name="~/Views/Partials/Modals/Image/UpsertModal2.cshtml" />

By the way my modal is working fine when not passing to the mvc controller but I need to populate my model first before loading the modal

Please, Anyone?
