Copy dataset fail

I’m trying to make a screen to display which dentists are present and in which waitingroom the patients can take place.
I created a dataset in Xibo which are all therapist are in with name and picture, with a filter the therapist are show on screen.
Now i want to copy the dataset several times so i have a dataset for each day of the week.
But when i copy the data set, the names become number and the pictures from library are not show.
Is this a bug or do I something wrong.
excuse for my bad english.
Hope to get a solution
Greetings Jasper
