Zwift displaying wrong cadence

Hello. While training on Tuesday, the cadence displayed on Zwift for the first half of my ride was displayed at 60 rpm. However, my actual cadence, which was displayed on my head unit was 90+. Zwift and my head unit were connected to the same cadence source, which is my power meter. In speak with others, they are getting the same issue. This started happening after the latest update.
