Lost a stash tab

So, Im not sure exactly how many tabs I had prior to buying one, but Im positive it just deleted one of my tabs and gave me another one. I had a tab that was only for inserting corrupted t14 waystones. I didn't put them into my Elons Maps tab for a reason. I bought a new tab because I was setting up my tabs for sales. Two of my tabs reverted their names, but kept the items. Now Im missing the tab that had my corrupted waystones.
