The "From presets" option in MPFB2 has disappeared

Somehow, the "From presets" option has disappeared in MPFB2.
I assumed this had something to do with cleaning up unused files and directories, and not saving MH models in the default location. So I reset MH to its default settings and saved a model to /home/ian/makehuman/v1py3/models, but "From presets" is still missing from MPFB2.
I have also tried uninstalling and reinstalling MPFB2, and even uninstalling and reinstalling Blender itself.
What can I do to get this option back?
