@Vaboon this is because there is no series Crid present in the guide which links the episodes of those programmes into a series so you are only offered the individual episode to record.
So a data ommission which could be due to the broadcaster data or the process whereby the data reaches the EPG on the EETV box.
EETV have some current issues with the data suppliers so until this changes you will need to set individual recordings is no series option is offered.
