Cursor position lines not visible in rulers

Hi there... it's a small thing but a huge pain in the butt for my workflow.  I've recently updated to the latest version of PS (23.4.1) and now the little lines in the rulers that show my cursor position aren't visible.  Is this a setting or a box I need to check or is this feature now gone?  I've been searching and searching but can't seem to find it.  Thanks for any help!
