I think we had this correct in the update script, but not in the main SQL. So updates would work, but creation from the maindata on a new install would have the issue. We've fixed to this (in other words, rather than fix the control, we've fixed the maindata script, because the update SQL was ok and matched the control correctly):
/*** New language strings ***/INSERT [dbo].[tblKartrisLanguageStrings] ([LS_FrontBack], [LS_Name], [LS_Value], [LS_Description], [LS_VersionAdded], [LS_DefaultValue], [LS_VirtualPath], [LS_ClassName], [LS_LangID]) VALUES (N'f', N'FormLabel_GDPRConfirmText', N'Please confirm you have read, understand and accept our privacy policy and terms and conditions', NULL, 2.9012, N'', NULL, N'GDPR',1); GO
