The Final Touches for the Extraordinary Adventures of G.A. Henty (Podcast Series) Keep Getting Rejected

I am almost done finalizing the Extraordinary Adventures of G.A. Henty (2013–2018) podcast series title here on IMDb, but the last few submissions for it keep getting rejected by the site.

For starters, on the "Under Drake's Flag" episode, Andrew Harrison's (I) "Show Announcer" (actor) credit must be set to Uncredited, as he was not credited for the role on the episode's website, unlike the other future episodes.

Second, for the following episodes—"The Dragon & The Raven," "Beric The Briton," "The Cat Of Bubastes," "In The Reign Of Terror," "Captain Bayley's Heir," "Wulf The Saxon," and "St. Bartholomew's Eve"—the whole series was recorded at "the Soundhouse" (in London, England), and there should be a Filming Location credit for each of the listed episodes: "Unit 10, Grapht Works, Victoria Rd, North Acton, London W3 6UU, UK" (this address is listed on the Soundhouse's website, so it's public knowledge); keep in mind that the address/filming location credit submission has already been accepted for the other episodes not listed here.
 

Third, for the "Captain Bayley's Heir" episode, there should be a "dedicated to" (Thanks) credit for Ronald Reagan (I); before you ask if this is the right Ronald Reagan though, think for a moment: what other Ronald Reagan do you know of?

Fourth, G.A. Henty was accepted and added to the title and all its episodes as one of its writers (credited with "based on the novel by" and an Uncredited tag), but for whatever reason, his credits are not visible anywhere.

Anyway, these are all of the submissions for the title that have been constantly rejected by IMDb so far; could someone help me get these submissions approved?
