Using the \appendix command somwhere in a KOMA-script document (in my case scrreprt) should change the behaviour of the enddot in a sectioning command: The chapters should only have an enddot if the numbering is in roman numerals (e.g. in the appendix) and otherwise should not have an enddot (according to the German scrguide).
\documentclass{scrreprt}
\usepackage[english]{babel}
\begin{document}
\chapter{Main}
\appendix{}
\chapter{Appendix}
\end{document}
The first compilation yields headings without any dot (even in the appendix). A secon compilation, however, yields dots in both headings. Removing the corresponding .aux file and doing recompilations reproduces the results. Moreover, the KOMA-option numbers=autoenddot does not change the results.
Is this the expected behaviour? Why are all headings with an enddot as soon as there is the \appendix?
\usepackage[english]{babel}has no effect. (In fact, I do not like the enddots in normal sections.)numbers=noendperiod.
