Errors double-up in list when affected fields are in multiple files

[SLornieCYC]

When an error has affected fields in multiple files/table the error description seems to repeat in the list for each affected file rather than once for "the error".

Although a simple "distinct errors" filter might seem an easy solution here, I would argue that where an error does legitimately occur multiple times (e.g. across several distinct episodes rather than one episode and an inter-related file) it would be useful to repeat the error description for each instance of the error (so the user knows to look for/resolve more than one).

Would it be possible to work out the distinct number of errors by calculating something like
count(rows in error across all files/tables) / count(files/table with affected fields) ?
Athough that assumes duplication is always a one-to-one relationship between rows in different files.. which probably isn't true!
