MacOS to Windows transfer: formatting problems

Hello, I’ve been using Skrivener on MacOS and have a complete novel in a project. In order to work on it abroad on my laptop, I recently bought Skrivener for windows. I saved a backup in the cloud and have just downloaded and unzipped it. But when I open it on Windows, there are formatting glitches. Some paragraphs have acquired bullet points, even though they have the same formatting label as in the original project. Re-applying that format leaves the bullet points there. Removing the bullet point using the list pull-down leaves me with incorrect paragraph indent.

It’s a long document; I haven’t checked for other formatting problems that might have crept in. Obviously, this isn’t workable. Have I wasted my money in getting the Windows version? This is a temporary measure. I don’t want to end up with a document on my Mac that has formatting issues that weren’t there before.

Thanks.
