Audiofiles

Hi. When i have created a slidshow in Adobe Elements 2021 Organiser I have imported adiofiles. I added 4 different files and when I preview the first time the first audiofile kept repeating itself. I´ve tried to save and move the audiofiles in different order but the next time I previewed the first adiofile was correct and the next adoiofile did´nt play at all but after that one the third was played.

(I´m knew at this program but have had Photoshop Elements 10 in many years and it´s frustrating that it
dos´nt work at all in the same way).
