Using code blocks within an admonition renders three copies of the block, weirdly enough twice before the description and once after. See screenshot for details.

I tried removing the code fence HTML definition but that doesn't make any difference.
The only console errors are about some plantUML issue. I tried removing all plantUML sections from the note on the off chance that it was related but that didn't make any difference either.
Only one code block should be rendered, the one after the description.
I checked on a different machine that was still running version 0.11.10 and the admonition code block was rendering fine. I then updated to 0.11.11 to check whether the bug was introduced by the update, but it's still working on this laptop.

Edit: Might be related to #2613. My other code blocks are rendering fine though.
I have the same issue on 0.11.11.
However, it renders just fine if I insert an empty line between the text and the code block.
Yup, that fixes it for me too. After a restart I was able to reproduce the bug on both systems, even though it worked fine one of them before. ¯_(ツ)_/¯
But the empty line is an easy workaround.
Came to here to report the same bug.

Sorry, I'm the sinful who have made the bug. :sob:
It've just created the PR #2622 to fix it. :pensive:
I have this bug as well in 0.11.11 on mac. Happens on all my notes


@wAuner sorry about that. The fix has been merged into the master branch so it will be fixed in the next release.
