SteamVR Bindinds not saving in project

We have had this problem before but I don’t know how we fixed that back then.

This is the problem I have.
We created SteamVR bindings the way you should do it by going to Window - SteamVR Input.
Then when I open the “Open binding UI” I select my project. And edit the binding per controller. When I have assigned all the actions to the buttons and want to save the bindings. Nothing happens. I can click on “Replace default bindings” or “Save personal bindings” or “Export binding file” but nothing happens.

When I select an installed game for example and adjust the bindings from the game then the saving works perfectly.

btw: it says that it saves my bindings to “documents/steamvr/input/exports” But that folder has only “export_openvr_tool_steamvr_environments_knuckles_My SteamVR Home configuration for Index Controller” in there.

Anyone who can help me out with this?
