When you first launch Lightroom Classic after updating to version 7.3 (April 2018 release), it displays a message about updating your custom develop presets (.lrtemplate) to a new preset format (XMP).
However, after the update is complete, you notice the following issues:

The preset conversion issue occurs in the following cases:
Lightroom Classic CC 7.3 isn't able to convert such develop preset files to the new XMP format.
With the introduction of new Presets and Profiles, the format of develop presets has changed from.lrtemplate to XMP. Lightroom Classic now converts your existing develop preset (.lrtemplate) to XMP format including the ones that contain a special character in their filename.
To update Lightroom Classic to the latest version, choose Help > Updates. For related information, see Keep Lightroom up to date.
Ensure the following for successful conversion of your .lrtemplate develop presets files:
Lightroom Classic also displays a list of presets that fail to convert.
To view your presets, go to Edit (Win)/Lightroom (Mac) > Preferences > Presets tab and click Show Lightroom Presets Folder.
When you launch Lightroom Classic CC 7.3.1 after updating, it automatically converts all your develop presets (.lrtemplate) to XMP again and appends double tilde [~~] in the .lrtemplate filenames that have been successfully converted. Automatic conversion is the best solution for users who have large no of presets and want to maintain their hierarchy. If you want those presets to be reconverted and used in Lightroom, you can manually edit these files and remove the appended double tilde [~~] from their names and restart Lightroom.
At each subsequent launch, Lightroom Classic checks for.lrtemplate preset files that haven't been converted. If present, it converts them to the XMP format.
To view the .lrtemplate preset files, go to Edit (Win)/Lightroom (Mac) > Preferences > Presets tab and click Show Lightroom Presets Folder.
After conversion, the new XMP presets are saved at the following location:
