Unable to complete album - sets

I’m trying to purchase a new album, one of two released by the artist this year, and the option to “Complete my album” is shown but will not allow me to make that purchase because several tracks included are already on an album I owned already!

No problem, but when I attempt to purchase the album full price, it gives the same error message and now I can’t buy it at all!

I’ve updated my iOS, signed out of iTunes and back in, help?!

(the albums in question are Megan, from April 2024, and Act II, from October 2024, both by Megan Thee Stallion)
