I'm having trouble using the editor to link to an anchor in another HTML module on the same page.  I recently upgraded from dnn3.x to 4.8.  Prior to my upgrade this worked perfectly.  I had quite a few HTML modules on a single page each referencing its own section using anchors.  I would use another HTML module at the top of the page to link to the other modules on the same page.  Now, after the upgrade, I can only link to an anchor that exists within the same HTML module.  Of course, I can go into the HTML source in the module and set the link, but the point is to use the Editor to do that work. 

I can't link to other anchors on the same page in different HTML modules.  Is there some environment issue I'm not aware of.  Is there a fix?  When I try to insert a link to another anchor I get the message, "No anchors available in the document".  Thanks in advance for your help.
