Unable to share all artboards and artboard are out of order

I need help.

For some reason, my Flow gets broken or corrupt and excludes some of the screens/artboards. There are times, when I will have developed 20 artboards, when I try to Share the project, the Flow will have changed to include only a few of the screens.  And they are not always in a series. They could be the first two, then skip about and include several others throughout the whole batch, but not all.

Anyone with suggestions on what I am doing to cause this?

Thanks, so much, for any advice.
