Secret Lair Rainbow Foil Pricing

It appears there is an issue with the Secret Lair cards that are marked as "Rainbow Foil" on the TCG website. For some reason, prices pull through in the Secret Lair Drop Series section of Editions & Printings, but the prices do not pull on the actual inventory. I checked numerous cards, and each one that had an issue was listed as a "Rainbow Foil" on TCG's website.

Example:
Acererak the Archlich inventory list pricing is N/A for TCG Player Market. The card has a listed price of $3.00 on the Secret Lair Drop Series section under Editions & Printings however, which appears to be the correct market price. There is some kind of disconnect between the price being listed under inventory, and the price being pulled for the specific "Secret Lair Drop Series' section.

Hopefully that makes sense!
