Preset names lost when applying style

Describe the bug

I have a preset that contains 2 instances of diffuse or sharpen, both built-in ones:

• sharpen demosaicing: AA filter
• local contrast

Previously, when I applied the style, the two instances were shown accordingly. Now, they are shown as:

The style contains:
