Actually, after I posted the above, it reminded me that I had a similar issue with a community plug-in (when I still used plug-ins) and not only did I have to disable it, but I had to reset its settings to the defaults, uninstall the plug-in, and then reinstall it.
It seemed like something was being cached somewhere, so even with the plug-in disabled, this issue was still there. After I did the above, the issue went away.
If that shows the numbers, then it’s just an appearance thing. Try again disabling all CSS snippets, returning to the default theme, and (for good measure) enabling restricted mode, and then restart Obsidian.
If that shifts right but still doesn’t show the numbers, than can you share a screenshot?
If that doesn’t shift right and doesn’t show the numbers, then can you press Cmd + Opt + I to open Dev Tools, press Cmd + Opt + C to use your mouse cursor as an element inspector, hover over the “10” line, and take a screenshot?
You can then free your cursor by clicking within Obsidian or pressing Esc.
I tried disabling all community plugins (Restricted Mode is turned on) and disable all CSS, restart Obsidian multiple times, plus I’m using Default theme but the bug still persists. And it only happens on my Macbook. The Dell laptop running Pop OS works just fine.
