Hi. According to your first email, the matrices are read from a text file. If the column/row names work in some parts, but not in other, then a possible cause can be that the text file contains the names in a form, which you do not expect. There may be a difference in case of the letters (names are case sensitive) or there may be white space in the names. Look at these names, they may be extracted using ?dimnames. Hope this helps.
