That was split in three settings (tension, compression and shear stiffness), but looks like updating the presets was forgotten.

@LucaRood-3 will fix that in the basic way (similar to our do_version code), but might be good idea to revise those new values to get closer-to-reality results maybe?

Indeed I forgot to update the presets, sorry about that. Regarding revised values, yes I could set some better ones, though it is a tricky matter, as cloth in Blender is unfortunately still mesh density dependent. Because of that, the presets can be extremely misleading, as people might get vastly different results, depending on polygon density. But in any case, I can make the values a bit more reasonable, as they are currently not very suitable for most cases anyway.
