When moving grouped items sometimes the arrangement changes positions

Hi ​@t.stone,

Thank you for posting in the Lucid Community!

Could you try opening your document in a private or incognito window to help us narrow down the potential cause? Could you also try connecting to a different network or disconnecting from your VPN (if applicable)? Sometimes account performance issues can be related to internet security/speed or browser issues. These steps will help us eliminate that possibility. For help with opening an incognito window, please see this community post.

Have you tried the following workaround when your item moves from back to front? Please try the steps (see screenshots below) to move your items to the back! If you have any questions, please review this Lucid Help Center article on arranging overlapping objects. 

If the issue persists, can you send the following:

• Which specific items are you using in Lucidchart?
• A screenshot or screen recording showing the specific issue (Unfortunately, we were unable to open/access the link to the video you provided)

Thanks in advance for your help and patience!
