Weird Thaumonomicon behaviour in Bismuth Projection

[KreloX]

Describe the bug:
When clicking on the bookmarks on the right in Bush Alchemy Specialization: Bismuth Projection, the first 5 (up to silver) work well, but when I click on osmium it opens a completely blank page (look at screenshot) and when I click on mithril it opens the page for osmium and to open the mithril page I have to click below the mithril bookmark. It seems that the clickable boxes are shifted downwards.

To Reproduce:

1. Install Planar Artifice + dependencies and Metallurgy 4: Reforged for the different metals
2. In creative mode, give yourself the needed research or "/tc research @p all"
3. Go into Thaumonomicon, into Planar Artifice tab and enter Bush Alchemy Specialization: Bismuth Projection
4. Try clicking on osmium and mithril bookmarks

Expected behavior:
When I click on osmium or mithril it would show the correct page.
