Also seen in Kubuntu 19..04 with PIM 18.12.3 packages
Comment 4 Volker Krause 2019-03-18 18:40:41 UTC 
Regression in kcmutils 5.56.0 it seems, with 5.55.0 the config dialog works as expected.
Comment 5 Volker Krause 2019-03-18 18:52:34 UTC 
Seems to be kcmutils commit ab33762a6a60101f6ddc5797e1620569f5a07a2a ("Sync QML module padding to reflect system setting pages"). David?
