Also submitted this via Support Case # 5832 on July 2nd.
For a while I've been seeing html codes replacing some punctuation marks (specifically apostrophe and ampersand, but there may be others) in the "Your Decks That Contain" results.
For example, I have a list called "Kaalia's Kites", which appears in the Your Decks That Contain results as "Kaalia's Kites".
And a list called Power & Profit, which appears in the listings as "Power & Profit"
Names appear correct in other locations.

Thank you for reporting these in detail, it's of great help when adding them.

I think one of the oversized Ikoria commanders seems to be missing.
"Gavi, Nest Warden" (Timeless Wisdom" Commander) only seems to have the standard sized version listed.
