Hi there, That doesn't sound like typical behavior. Could you please let us know the exact version of Photoshop you're working with? You can check the exact version of Photoshop by going to Help > System Info. Also, please try resetting the preferences of Photoshop and let us know if it helps: https://helpx.adobe.com/photoshop/using/preferences.html
Note: Make sure that you back up all your custom presets, brushes & actions before restoring Photoshop's preferences. https://helpx.adobe.com/photoshop/using/preset-migration.html
