Lightroom no longer using built in lens correction

[SC Oly User]

Prior to the latest update to LR 14.3.1 LR used teh built in lens correction and this was shown in the develop module under the Lens Corrections tab. It currently shows the Enable Lens Corrections is ticked and it sets to default. It does show the correct lens and claims ti use Camera Settings. However, it does not correct distortion as completely as it did in earlier versions of  LR. I am using the OM Systems OM-1 and the Olympus 14-150 Mark II lens.

Try resetting the preferences of Lightroom Classic:  How to reset Lightroom Classic preferences (adobe.com)

It's recommended to backup your preferences before you reset the preferences to the default settings:

Perhaps you can explain why resetting the preferences would help. I did not set any preference to use or not use the built in lens corrections. LR did this automatically with its software.

Take a look at this post by @johnrellis

where he writes

"LR stores a large amount of internal application state in the preferences file, not just user settings, and if that state gets recorded inconsistently, then chaos in the user interface results.   Unfortunately, the preferences implementation has a design flaw that makes it too easy for LR to store inconsistent values."
