Yes, this is caused by caching. The propagation of the update to Hubspot's (Cloudflare's) CDN takes a bit of time, and I've found that's especially true for blog template updates. Can take 5 to 10 minutes sometimes.
UPDATE: The site works perfect in preview and with the --> ?hsDebug=true ending. This is the experience i want for the end users. Guess its some kind of cache?
