Histogram detail missing

[Heirloom Bob]

A friend with Lightroom Classic on a Mac has all of a sudden, lost ISO, shutter speed. f stop etc info from the bottom of her histogram.I am pretty sure it's something she has done but for the life of me, I can't figure out how to get the missing info back. Thoughts? Photos from a few weeks ago, have the info show but not the newest shots?

You would not happen to be cropping while this occurs?

During some edits, cropping comes to mind, the histogram info you are refering to will not be shown.

David,,,no that is not the case.

On my Windows computer, Lightroom 9.2.1, if my mouse points at the image, the histogram shows the RGB values. If my mouse points at the histogram, then the ISO shutter speed f-stop etc appear under the histogram.

If an image is exported without sufficient metadata, and then imported back into Lightroom, this will happen, and the Histogram will look like this:

To include the camera data, choose include All metadata in the Export dialog.

Sorry all...significant operator error. Histogram info I was "missing" only appears in Library module, NOT Develop module! Sheesh...I am embarrassed.

on Mac it does appear in Develop Module, Only issue I have is the small Over and Under exposure triangles no longer appear since I did the update.  See attached screen shot.
