If your tabs included special characters (such as &, > ) it is probably not displaying properly. The right arrow (> ) displays as > for example. The & displays as &.
To correct this, you need to edit your tab. Simply opening the tab in edit mode, then scrolling down and clicking on ‘OK, Go’ will fix the >. To fix the & you will need to delete the extra characters (amp; ) while in edit mode.
I don't know if other characters (~) need to be fixed.
