On Adobe Bridge version 14.0.1.137, on Windows 11 Razer Blade 15 (2018) laptop.

When attempting to save HEIC images to smaller JPEG formats using Export Presets, the resulting images are being resized, despite the Scale Image setting under Image Resize being set to 100%. In my tests, 4032x3024 images are being resized to 2048x1152. Also, the DPI is changing to 300 dpi from the original 72 dpi, despite this not being requested.
Attempting to use the 'Resize To' option also fails. Setting options to fit the long edge to 5000 px, and checking Don't Enlarge, still leads to 2048x1152 images, although at least when setting the DPI to 72 here, it keep it as 72 in the result.
