When "combine results" action is executed and error in S(D)V/M calculation occurs, the warning message does not say for whit measure data it happened, just:
Matrix does not contain any valid values.

Also the message:
Found not all requested standardised distance matrices/vectors for selected files
should be rather:
Not all standardised distance matrices/vectors present for selected measures
or maybe even more specifically:
Missing standardised distance vector for selected XXX, YYY, and ZZZ measures.

When the error occurs the user selection is lost (choice of action, selection of measures). It would be nicer if it is kept, so the user could easily execute the action again.
