Encountering errors when trying to read certain classes from the device

Hello there.

I have been using the GXDLMS app to communicate with a data logger I have been developing.

After recent update, I am unable to use two classes - LTE Monitoring and Push Setup. Below I have included the specific errors received when trying to interact with these

Push Setup: (I am using version 3)
System.IndexOutOfRangeException: index
at Gurux.DLMS.UI.GXDLMSPushSetupView.OnAccessRightsChange(GXDLMSViewArguments arg)
at Gurux.DLMS.UI.GXDlmsUi.UpdateAccessRights(IGXDLMSView view, GXDLMSClient client, GXDLMSObject target, Boolean connected)
at Gurux.DLMS.UI.GXDlmsUi.ObjectChanged(IGXDLMSView view, GXDLMSClient client, GXDLMSObject target, Boolean connected)
at GXDLMSDirector.MainForm.SelectItem(Object obj)

LTE Monitoring:
System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
at System.ThrowHelper.ThrowKeyNotFoundException()
at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
at Gurux.DLMS.UI.GXDlmsUi.GetView(Dictionary`2 views, GXDLMSObject target, Standard standard)
at GXDLMSDirector.MainForm.SelectItem(Object obj)

Do you know something about these issues?

Sincerely,
Klimmie
