Ugly-Ass Font

While I love using Wix for the most part, there is one bug that, well, bugs me. I'm trying to keep a consistent look on my page by using one font (Times New Roman, because High Tower wasn't available) across my site, but for some reason, only on the Blog page, once you click into any post, no matter what font you select for post headers, when you publish, Wix switches it back to that ugly-ass font. It shows up with the correct font before you click, but once you click, you're stuck looking at that wildly inappropriate font. I even tried deleting my Blog page and the Blog App from my Wix account, and then redownloading, and recreating my posts from scratch, but the post titles still show up in that eye-gouge-inducing font, like a turd on the platter of a 7-course meal. If anyone can fix this or knows of a work-around, I'd appreciate the help.
