Cannot find 'Extras' and 'Versions' section in movie information page

[psc1453]

Hi, thank you for the impressive skin! I installed your skin on KODI 21.0 but I cannot find 'Extra' and 'Versions' section in movie information page which can be use in KODI's default skin. I have tried to enable all the items in management-settings inside the movie information page, bot there is no option for 'Extra' and 'Versions'. Also, in the movie list's context menu, 'Manage Versions' will crash. Could you please offer me some help if my operations are not correct? If there is no such option now, could you consider to add them in future updates? Thank you so much!
