My psd1 version and psgallery version don't update.

[mgeorgebrown89]

Hello, I'm using this module and the BuildHelpers one to publish my module to the PSGallery with AppVeyor. When I !deply without manually changing the version number in my psd1 file, I get an error on the deploy section stating a module with the current version already exists. If I manually update it, it deploys it, but the version number is one ahead of what's actually in the psd1 file.

I'm not sure what's going on. I've tried looking through the modules themselves but so far can't seem to figure it out. This is the module, in case that helps: https://github.com/mgeorgebrown89/PSlickPSlack

(I realize I may have duplicated some things in my module, but there wasn't much in the way of their new Slack Blocks, and I've been using it with a bot/app I've been building, but these pieces don't have to be specific to my company).
