Issues saving group as pdf

I used to be able to select multiple tabs within in excel workbook (as a group), then click Save As, change the document type to PDF, and save the grouped tabs as a PDF with multiple pages. Somehow, my computer no longer lets me save the group as a PDF and instead only saves one page of the group as a PDF. Does anyone know if there is potentially some setting that has been changed that I need to reset, or even where I could find options related to saving excel groups?

Thanks!

I group tabs and then save them as .PDF very often . Make sure you select each tab with CTL-click

It's something I've been doing for a while and only recently stopped working. I select each tab with the ctrl button and they are clearly highlighted, but as soon as I hit Save As, all of the tabs but the first one get un-highlighted. I'm not sure if there is some random option somewhere that automatically ungroups tabs after hitting save, but thats what its doing.

I have had that trouble in one of my computers and it seems to be the click button , sometimes it clicks wrongly...
