PG version 8.3 issues

I downloaded and installed Pine Grow vversion 8.3. and it is acting very “flaky” - the UI doesn’t function properly. (e.g, dragging a header from the library to a column placing it by using the tree) breaks the entire page that contains rows with columns inside a container. There are other misbehaviors like saving a page as a copy also breaks the layout. I’m using a Macbook M3 14inch (Nov 2023) with 8GB memory. I’'m attaching both a caapture of my editing sreen and my code. Any help?

Hey Randy,

There aren’t any known reasons for this behavior, whether it’s with Pinegrow 8.3 or an earlier version, so I suspect it might be an external issue. Please reach out to support so we can take a closer look at your problem.
