Tabs Self Deleting

I am having a issue with the tabs self deleting. I often have to recreate the tabs several times before I can get them to stay. Occasionally I have had them disappear on a file I had saved and then reopened at a later time.
Appreciate any thoughts. ’

Are you using a current version of Carbide Motion? If so, please send a file which repeatably exhibits this behavior and step-by-step instructions for causing it in to us at support@carbide3d.com and we’ll do our best to look into this with you.

I have experienced something similar. Sometimes I recycle a design that already has tabs. The tabs show up but are not cut. Also I can add new tabs and they are cut but the existing tabs do not usually cut on a file that re-opened. I am using CC 4.64
