Commands in Customized Ribbon Tab Keeps Disappearing

This issue where your custom ribbon tab remains visible but the commands inside it keep disappearing is likely due to Excel resetting or not properly saving the customization. Here’s what you can try to resolve it:

First, make sure you are exporting your ribbon customization after setting it up. Go to File > Options > Customize Ribbon, and after setting everything up, click Import/Export at the bottom right and choose Export all customizations. This creates a backup you can quickly reload if Excel removes your commands again.

Also, check if any Excel add-ins, updates, or profile syncs (especially if you use OneDrive or roaming profiles) might be overwriting or resetting your UI settings.

If this keeps happening after system restarts or updates, try running Excel in Safe Mode (Excel /safe) and see if the issue persists. If not, an add-in might be causing the reset.

Let me know if you're syncing your settings across devices or using any management tools like Intune or GPOs, which could also be contributing.
