Screenshots of the actual bleed area and the export dialog showing the bleed settings would help.
Does your InDesign layout actually have objects that extend into the bleed area?
(Sometimes it's assumed that 'bleed' is an automated feature, but it is only an inclusion of the specified area beyond the page boundary. The layout must include objects which occupy that area.)
If you answered yes, it might help to post a screenshot or two showing the layout before and after export.
ALlthough you mave set bleed for the InDesign document itself, beware that in default PDF export options the bleed for that PDF is always set to zero. So you have to set the bleed seperatly in the PDF as well. Either use the Use documents bleed option or just set it yourself in the PDF export settings in Marks and Bleed.
You were right Frans van der Geest!
I found out by my self, but what you replied was the answer to my post. Thanks anyways and thank you all for replying
