Issues Recoloring Country Charm Island from Country Kitchen

Hi there, I am working on my first recoloring project, and have run into an issue with the Country Charm Island from the Country Kitchen Kit. I've been recoloring the counters and sink with no issue, but I think there might be some texture files missing in S4S for the islands. With the available textures I've been able to recolor the center and the two rounded island pieces, but the rest are still the original colors.

I am using v 3.1.5.8. Wishes and Adobe Photoshop CS4 for the recoloring. My Sims 4 should be fully up to date, the version is 1.88.228.1020 and includes the pronoun updates. I would appreciate any advice if there is something I am missing!
