Not working in Obsidian 1.3.4

[merlinuwe]

Thanks for your great plugin.

When I use it in Obsidian 1.3.4 and with Minimal Theme, it shows the numbers only, when I change to button position. (Regardless of the direction.)

When I scroll a little bit, the H2 dissapears.

When I use Standard Theme, it nevers shows the header numbers.

What can I do to get it running?
