When I use "Save as new title" on a modified Motion Title, I expect that I can re-use this new title when selecting TITLES & TEXT and then the category CUSTOM. This works at first, but after a restart of the PE14, the custom title becomes what seems to be a sub-category under CUSTOM and the actual title is nowhere to be found. Instead, all motion titles of the same sub-category "Typography" can be found there.
May I know the operating system that you are using?
Meanwhile, You can try saving any other Motion Title as new Title and then check whether you are able to get previously saved Titles or not.
