Take heart. I found at least
3 4 obvious m/m romances on the first 5 pages alone, just by looking at the cover images*. So it probably won't be like looking for 5 needles in a 25-page haystack.
I advise using Firefox and turning the "picture zoom" function up high so that it's easier to spot the Spectrum LGBT line banner on the cover art for the ones that are less obvious about having two naked male torsos on the front.
Also, you might want be sure to note the length on the side. Some of them are just short tie-in novellas going for the same price as the full-length series novels.

Cyr's Revenge (bounty hunter),

Joshua's Moon (college student),
Fighting for Eternity (vampires).
