formula notation not correct
Describe the problem you encountered

should be something like [2M+H]^{2+}
Documentation version
See also my comments: https://github.com/OpenMS/pyopenms-docs/pull/331#discussion_r1109580670 please double-check if they all were fixed.
And no, it should not be [2M+H]^{2+} but [M + 2H]^{2+} . Please note the spaces and the fact that it is not two times the precursor but the precursor with two additional hydrogens.
In pyopenms-next?
