Cubase 10.5 automatically changing stereo channels to mono

I am having a weird issue with 10.5 and it’s never happened before. For some reason, Cubase is automatically switching some of my stereo channels to mono. I have gone back and forth with creating new stereo channels, which works fine and then ten minutes later, it’s been turned into a mono channel. I’ve searched online and as much as I could in the forum but haven’t come up with any info. I’m running it on a late 2013 Mac, 2.3 ghz, 16gb RAM with OSX 10.14.6 and Saffire Pro 40

Thank you in advance for any help!


Are you really sure about it? It’s not easy to convert the channels in Cubase, it’s quite a process. I don’t believe this happens by itself.

Yes this has happened to me too .I have spent hours on it and its just changed for no apparent reason.and is OK must be a bug. Its when I sent my tracks to a stereo group. The bar graphs in the channel became mono Have similar system but using Macbook pro 2011
