It seems reftex mistakes labels in tikz nodes with genuine \label 's in
LaTeX
source.
To reproduce:
1) open a buffer foo.tex in LaTeX mode
2) insert (via cut&paste) the following text
\begin{figure}
\begin{tikzpicture}
\node at (0,0) [label={node 0}] % not a LaTeX label
\end{tikzpicture}
\caption{Figure that!}
\label{myfigure} % only genuine label
\end{figure}
3) M-x reftex-toc
4) in the TOC buffer, hit key l for reftex-toc-toggle-labels
5) now the TOC buffer shows a genuine LaTeX \label and an irrelevant
tikz node "label".

Does adding "tikzpicture" to
reftex-label-ignored-macros-and-environments work?
--8<---------------cut here---------------start------------->8---
reftex-label-ignored-macros-and-environments is a variable defined in
‘reftex-vars.el’.
Its value is nil
You can customize this variable.
This variable was introduced, or its default value was changed, in
version 24.4 of Emacs.
Documentation:
List of macros and environments to be ignored when searching for labels.
The purpose is to ignore environments and macros that use keyval
style label=foo arguments, but the label has a different meaning
than a \label{foo}. Standard \label{...} definitions are never
ignored.
E.g., TikZ defines several macros/environments where [label=foo]
defines the label to be printed at some node or edge, but it’s
not a label used for referencing.
Note that this feature is only supported if you are using AUCTeX
and the functions ‘TeX-current-macro’ and
‘LaTeX-current-environment’ are bound. Also note that this
feature might slow down the reftex parsing process for large TeX
files.
--8<---------------cut here---------------end--------------->8---
In what's going to become Emacs 27.1, we are a bit more conservative and
have a whitelist of environments in which we look for label=foo options.
There, the bug doesn't happen anymore, so I'm closing this bug.
Thanks,
Tassilo
