LRC does not identify Sony lens

Question

I am having all sorts of issues lately, but here is one that just bugs me.

When I am working on an image, I identify the lens, in this example it is Sony 70-200 GM. I export to PS to do some edits. I reimport to LR and it identifies for me the lens but it is wrong. It does this with a Canon wide angle lens I use as well.

In the example I attached LR is choosing an 18-200 lens, which I don't even own. Anyone else have these issues?

Then it's no longer a raw file, it's a rendered RGB file. It's not the same file! At this point, the lens profile has already been baked into the pixel data. You' don't want to apply it a second time, do you? Lens profiles in Lr are for raw files.

An RGB lens profile may or may not exist, but it would be applied in Photoshop, not Lightroom. And then you better make sure it hasn't already been corrected in the raw stage.

"I export to PS to do some edits. I reimport to LR and it identifies for me the lens but it is wrong." The Lens Corrections panel doesn't show you the lens recorded in metadata -- rather, it shows you LR's best guess as to which lens profile should be applied. The file returned from PS is a non-raw (TIFF or PSD), and there are very few lens profiles that work with non-raw.  LR is showing you one of two profiles for Sony lenses that works on non-raws. In general, apply the lens corrections to the raw before you edit in PS.  The correction will then be included in the TIFF or PSD returned from PS. If you just want to see the lens used, rather than apply a correction, use the View > Loupe Info > Cycle Info Display command (see the menu for the keyboard shortcut).  Or look in the Metadata > EXIF panel in Library.
