Documentation vs Homarr version

This might be a stupid question but how exactly do i find the correct documentation version ?? I just installed homarr via. https://github.com/ajnart/homarr/pkgs/container/homarr and have version 0.15.0 installed which should be the latest. However when selecting the documentation version the newest seems to be 1.14.0. I noticed that a lot of features described in the documenation seem to differ from what I'm able to do in Homarr. Example: https://homarr.dev/docs/getting-started/after-the-installation/#using-dynamic-sections describes how to use dynamic sections; however the button and dialog to add items looks completely different on my side and the "new dynamic section" option is not available.
The documentation seems to describe a version which differs significantly from what I'm working with.
I already asked kapa but was unable to get any helpful feedback. I would appreciate any feedback.

Additional information:
- Screenshot of my dialog that opens when selecting "Enter Edit Mode" > "Add a tile". this differs significantly from the dialogue and options described at https://homarr.dev/docs/getting-started/after-the-installation/#arrange-and-organize-your-board.
- Screenshot of Homarr About Section.
