Is it possible to index the sub sections of an Appendix, both in the table of contents and the Appendix itself? At the moment, what I am getting is something like the picture attached; The subsections are indexed in both locations, yet the the capital letter (e.g. A) is missing and the numbering starts with a dot (.). Any ideas?
EDIT1: The same issue appears in the "List of Figures" and "List of Tables" as well. In that case, apart from capital A, dot is also omitted.
EDIT2: Here is the project.
