Appendix not working correctly

[Max B�lhoff]

Hi,
The last part of my current Lyx document is an Appendix. For this I
switched on the Appendix in the menu. The problem is that in the final
output file (Postscript)  �Appendix A� is shown correctly, but all the
following ones are displayed as �Chapter B�, �Chapter C� etc. instead of
�Appendix B�� This is both in the table of contents as well as in the
actual headlines.
Does anybody know a solution?
Thanks
Max
