Only the episodes broadcasted originally on TV are part of the regular seasons. The other are part of the specials season.

You need to use an episode group if you want another grouping.

i know what your mean，but when we editing grouping，the data is from basic or main season，the problem is the basic data is undefined（no title），can you edit the title？

Hello @Mioo

You seem to be confused. The Chinese data for those episodes was wrong, specials 10 to 12 are episode recaps. The special you are referencing in your report is actually 0x6. I recommend you to check the Japanese translation to properly sync the needed information in Chinese.

As for 0x10, 0x11 and x012 titles: Unless the recap episodes were officially released on China, the title field should be left blank. If they were aired or properly distributed please do re-direct to us to a reliable source. Thanks.
