Custom Presets Lost their Custom Source Crop Settings - Reset to 0

I have a few dozen watch folders, with custom presets for each one. They crop the video (under Preset Source) then apply an overlay.

Works perfectly... until today.

Every Custom Preset in my list, the Source Crop has been reset to 0, 0, 0, 0. Now the video under the overlay has an extra black bar, because the video is "too wide" under my overlay.

Even though I backed up the Preset file, with my customs, I do not see where the CROP LEFT , RIGHT, TOP... etc appears in the file so I might try to fix with a find/replace rather than manually set each preset again.

I anticipate having MANY MANY more folders and such Presets in the future, where such a "glitch" would ruin my workloads.

Any ideas on how to prevent / lock these Presets from being glitched by updates? Or how to fix the current present file with a search / replace?

Thank you!
