Issue of Filter Camera Raw with Photoshop Photomerge

Hello. I'm using Photomerge in Photoshop (V. 21.1.0) with some vertical images (taken by my iPhone 6s) to create an horizontal panorama but when I apply Filter Camera Raw (V. 12.3.0.493) in the CR Filter the horizontal image is rotated automatically in vertical so it's impossible work in CR Filter. To solve I have to save image, close it, then open and apply CR Filter with the image horizzontal. This is not a solution so I ask here if is there an option to fix this issue? I hope it. Thanks.
