Ok, in my project the right yellow marker was hiding behind the modify tab and not visible which probably caused the confusion. Please ignore my report, its clear now that the green markers are for export, the yellow markers for preview loops. They both work perfectly !
Hi K_Digital Thank you for your feedback. I'm not sure if your Timeline has the "Set Start / End Frame" feature. After you press the Set button, the markers for the "in" and "out" positions in the Preview will appear, and after playback, the loop function will work properly. I'm not sure if I have been of any help to you. :) Kayla Realluison
Please do not be confused with timeline and play bar Loop. Above i meant the Loop Button in the play bar isn working as intended.
