Saving format changed to Window PCM(*25.*.wav.*bwf) when 25 was never in it before and wont play as

Hi i wor k in a radio station, Tamar Fm in Australia and we have used adobe audition 3.0 for many years now, yes it's old but reliable and simple to use and since yesterday the save format changed from PCM without the 25 in it..... Window PCM(*.wav.*bwf) ........          to now suddenly including the 25........ Window PCM(*25.*.wav.*bwf) ........    and it becomes unplayable as a wave file after what was recorded is saved and our radio system heavily relies on wave files rather than Mp3s and i understand there is wma but it's odd how this has changed to 25. Could anyone please help us with this issue. From the bottom of the world aka George Town, Tasmania, Australia i say Kudos in advance for reading this and any advice would be so much appreciated
