duplicating an album on a portable flash drive

As a "non-cloud" backup, I wish to duplicate my Albums from the Photos program on a portable flash drive. I am given the choice of doing this by "Album name with number", "by title", "by original file name", or "sequentially". However, once the export is done, none of these choices produces a copy that duplicates the original setup of the album ...in the original album I have given a title to each photo and then arranged them in my own choice of sequence. "Album name with number" and "sequential" puts them in order but eliminates the titles. "By title" gives the titles but then arranges these alphabetically. "Original file name" just gives the original image number from the camera and is of no use.

I believe when I used Yosemite I managed to get an exact duplicate album but now with El Capitan, I'm having no luck. I have searched extensively for answers to this question, but have not found any answers. Any one's help will be appreciated.
