In Logos, I study theology books by taking notes in a different application, marking down the page number and pasting quotes of interest. That way I don't always have to open the resource again if I want to quote & cite it in something.
This month, I read the preview book, Sproul's Everyone's a Theologian, almost exclusively through the web app. Going back to my desktop and checking my quotes today, I notice that the page number I have recorded, which I took from the "Go" field in the web app while reading, is always +1 page numbers ahead of what the resource is showing in Logos desktop.
For example, this passage is shown as being on p. 30 in the web app:

Versus the orange page marker in the desktop app, showing page 29.

I have noticed this problem in other resource as well. Is this a bug or is there something I'm just not perceiving correctly? For casual reading this is not a problem, but for citation in formal writing it is a major issue.
I need this clarified so I can know how to proceed with occasional use of the web app. If all resources are consistently numbered +1 page, I can work around that BUT notify us if you ever fix it. If it's not consistent I'll have to double check every single citation I make from the web version against my desktop version, which somewhat defeats the purpose of having the former.
Someone from Logos, please advise.
[For the record, while I never used biblia.com that much, I had previously noticed this problem there too but didn't think much of it at the time.]
