Phal Gigantea Brown Spot on Stem

[KatieM]

Hey, guys. Just received my first ever Phal Gigantea yesterday (well I got 2 because they were on sale lol). I noticed at the base of the stem on both PG's there's a brown spot. It's not dry, almost seems mushy. I'm assuming I received infected orchids. Thoughts on what this is and how to treat? Thought about trying to surgically removed the area and treat with cinnamon? Doesn't look like any black rot I've experienced but I've never had a Gigantea either so any advice is appreciated! Haven't even potted them yet. Wanted to get this under control right away. I live in N FL and am a primarily outdoor grower. Thanks much!
