Design Studio SDK: Planning Calendar Component

[FHasba1204]

the component was working fine, after updating to Lumira Release 2.2 SP0 Patch 1 the component is not showing the Title of the Rows.
we are filling the component per script, here is a code snippet:
we tried to test it like this but no luck.
PLANNINGCALENDAR_1.addRow("123", "123", "123"); PLANNINGCALENDAR_1.addAppointment("1234", "123", "20190101", "20190201", "TEST", "123 TEST");
