FX Modulator pre-sets disappeared from Cubase 13

When I try to load pre-sets, I get a blank table.
If I’ve loaded a FX Modulator pre-set into a track in Cubase 12 and Import it into
Cubase 13, the pre-set appears but the pre-set table remains blank.
Beginning to wonder if I’ve been fobbed off with some beta version of
Cubase 13.
Anyone else having this problem?
