I just noticed that some of my local files do not show up in my bookmark that I set-up to show local files when my Tidal account is enabled.
With the bookmark selected and the Tidal account enabled it looks like this:
As Greg suggested, try settings Show Hidden Tracks and Albums to Yes.
Most likely you also have these albums in TIDAL, and the TIDAL versions are set as the primary version. By default, if there are multiple versions of an album, only the primary version is shown and the rest are hidden. They can be accessed by going to the Versions tab of the primary album, or you can unhide them with the setting mentioned above.
