Local adjustments and filters on photos get removed when using Keys in LRC 9.3

[cajames]

Steps to reproduce:

1. Add a local adjustment brush to a photo, and deselect.
2. Add a radial filter to the photo, and deselect.
3. Then use VSCO keys to adjust some other setting, e.g. exposure of the photo

The local adjustment brush from Step 1, and the radial filter from Step 2 are removed.

This issue only affects local adjustment brushes and filters (radial and graduated). Clone/Heal stamps, as well as crops, are not affected. Neither are any other development settings.
