Bulk export of PDFs to Tiff Multipage

Hello and Thanks in advance for your help

I am having an issue with Adobe Acrobat DC where I can export a PDF to a multi page TIFF file when only exporting 1 file at a time but if I try to use the action menu and export a folder worth of PDFs to TIFF files each page in each PDF saves as a separate TIFF file. I have gone through the options but can't figure out how to get around this. Is there something simple I am missing?
