Seasons are misplaced for specific show

I've checked correction page (Updating Information for "High Rollers DnD") and seems there is no transparent way to do the necessary edits, just a hundred submenus not similar to something like "correct season names".
Can you please elaborate exact steps?

So they have now "Season 3" which have
S3.E1 ∙ Altheya: The Dragon Empire #1 | A World of Stories (Part 1)
S3.E2 ∙ Altheya: The Dragon Empire #1 | A World of Stories (Part 2)
S3.E3 ∙ Altheya: The Dragon Empire #2 | What's Yours is Mine (Part 1)
S3.E4 ∙ Altheya: The Dragon Empire #2 | What's Yours is Mine (Part 2)

but it should be "Altheya - Chapter One: A Humble Beginning" which have
E1-E6
And then 100 more EP's
How can this possibly be edited or suggested?

On any episode, scroll down to Edit Page. There, scroll down to Other Corrections -> Episode Title/Number. Select Correct from the drop-down menu. You can now add or change the episode number (in the format of "season.episode", e.g. "3.1") and title. 

You can find detailed help and instructions to submit the corrections in our Help Articles.

@Fran​ Thanks, there is some improvement now. But big deal is that each episode here have two parts. I.e.
S1E1 Part 1

S1E1 Part 2
All my contributions trying to drop two parts into the same eps were rejected.

GPT said this is case where only staff can help?

Anyway, is editing manually 100+pages (=wrting a auto page opening script which will do this instanity) is the only way to properly fix this?
IMDB have hundreds of developers to improve editing tools and none of them can hadle this? Do we really need to fix this in the most frustrating way? What if the next contributor don't know how to write and debug auto page opening scripts?
