For the Lens Correction panel, can we see a screenshot please?
For the labels, go to Metadata menu > Color Label Set and put the names back to match the names of the labels you were using previously. White labels just mean that the 'name' of the color label doesn't match any of the colors in the current set. You can check the Metadata panel to see what those names were, if you can't remember.
Also go to Preferences > Presets tab and check Store Presets with Catalog and see if your Print Presets and other settings come back. If they don't, you can uncheck it again.
