P: Local adjustments and crops don't copy or work in presets applied to rotated photos

I can duplicate your issue using the Sync settings as well with Lightroom 6.10. I will file a bug on it. Thanks for the information. 

As I experienced, when graduated filter mask is copied from LANDSCAPE format image to an other  with PORTRAIT format, the mask keeps its position fixed to the frame relative to the image borders. While radial filter and brush mask rotates with image, following the camera rotation direction (exactly the bitmap). Of course there is not much sense, to copy masks without changing position between different formats, as they must be different compositions, BUT two following  portrait format image can be the same composition, while photographer changed camera rotation between shots. So lightroom should apply the "camera rotation exif info" when pasting masks. ...naturaly, to perform this, it should compare this infos between two pictures....for this, copy settings command should copy the rotation info too, and paste command should perform comparison. If they are the same, masks can keep positions correlate to the bitmap, if they are opposite, masks should be rotated 180 degree.  

Going on with this idea: can it be true that the radial filter and brush filter is"bitmap related"  in lightroom, while graduated filter is " frame related?

I made two portrait format pictures  of myself in mirror to demonstrate the issue.  (See Screenshot 1 and two ).As you see on first photo I rotated camera 90 degree CCW (so the grip is up)

on the next I hold camera rotated 90 degree CW (so the grip is down.)  
In Lightroom I made a radial filter  on picture one with exposure +1.2 value to bottom right of the picture (on my t-shirt). Then I copied the settings (included Radial filter) and paste to second picture . As you can see, the filter appears at the upper left (where the tulips are). As I think it about (I'm not software expert or programer at all) this can couse the issue:The cameras position sensor takes data to exif info  about the rotation of camera. This data refers which corner of the picture is bottom left (for istance) correlate to the bitmap of the file. As this data applied  all two pictures appears in correct position when wieving .  But -for some reason- this data is not applied, when position related modifications -are pasted from one picture to another. An addition: After my first post, I tested, that the same issue happens with brush filters, but  with graduated filter NOT. See screenshot 3 and 4.)

Bela,
Can you post to a snapshot to explain the issue. Its not fully clear.
