Tvheadend

If I program a recurring recording it seems that from some channels, libreelec do not detect which programs are part of series. Recordings from one Danish public service broadcaster (DR) are placed with one episode in one folder for each episode. The folder is named by the name of the Recording, followed by (2_4), (3_4) and so on. However the title of the single episode inside each folder, is named followed by (2:4), (3:4) an so on.

A series from the other main Danish public service (TV2) seems to placed as expected with all episodes collected in one folder. In this case though - I would have liked the folder name to not include any episode infomation - now is says (2:8) but the folder contains several episodes.

Any ideas how to improve this?
