Beamer showing duplicated slides when hiding notes

Question

The presentation often uses multiple note pages per frame (\note<2>{text}) resulting multiple slides.

Consider a frame with no overlay specification itself and is just duplicated to more than 1 slide because of overlay specification on the notes. Using the \setbeameroption{hide notes} will remove notes but the frame still has more than 1 slides which should not have. How I can remove duplicated slides?

\documentclass{beamer}

\setbeameroption{hide notes}

\begin{document}

\begin{frame}
  Slide 1
  \note<1>{information}
  \note<2>{more information}
\end{frame}

\end{document}

Does anyone know a way accomplish only 1 occurrence of each slide? Maybe by some option for beamer or the way the notes are setup.

Answer 1

The following MWE should give you the desired result of a single frame and two note pages:

\documentclass{beamer}

\setbeameroption{show notes}

\begin{document}

\begin{frame}
  Slide 1
\end{frame}
  \note{information on the first note page}
  \note{more information on the second note page}

\end{document}

In comparison to your code, I have moved the \note commands outside of the frame environment. However, please keep in mind the following from the beamer manual (See "19.1 Specifying Note Contents", page 204):

To add a note to a slide or a frame, use the \note command. This command can be used both inside and outside frames, but it has quite different behaviors then: Inside frames, \note commands accumulate and append a single note page after the current slide; outside frames each \notedirectly inserts a single note page with the given parameter as contents. Using the \note command inside frames is usually preferably over using them outside, since only commands issued inside frames profit from the class option onlyslideswithnotes, see below. Inside a frame, the effect of \note⟨text⟩ is the following: When you use it somewhere inside the frame on a specific slide, a note page is created after the slide, containing the ⟨text⟩. Since you can add an overlay specification to the \note command, you can specify after which slide the note should be shown. If you use multiple \note commands on one slide, they “accumulate” and are all shown on the same note. [...] Outside frames, the command \note creates a single note page. It is “independent” of any usage of the \note commands inside the previous frame. If you say \note inside a frame and \note right after it, two notepages are created.
