Hi. Thanks for uploading the video. I followed the steps you made and I don't get the same behaviour - the functionality works as you would expect without any issue. I'm guessing then that it's something to do with your browser or its settings and it's conflicting with the autosave feature. I'm using Edge and it's on the latest release. I'd suggest trying another browser or disabling extensions to try and narrow down the issue, but you might just want to contact SmartBear support - they are usually quick to respond. You can reach them at the link below. I'd be interested to hear what the issue was if you'd like to share!
