Paths transforming when added into existing WPF-Project (.NET 5)

Question

I've been coding for about year now and this seems to be the time I acutally have to ask a question here, cause I think I'm losing my mind.

I'm coding a "Diagnosis Picker" for a WPF-Desktop-App to simplify classification of fractures.

Goal is to color in each bone, when the mouse enters the according Area. Here u can see the outline, here the Areas and colored in bones.

So I converted everything into paths with inkscape, exported as xaml, copied into a usercontrol, made the areas transparent, collapsed visibility on the coloring in and added events for MouseEnter and MouseLeave on every Area.

Code behind:

public partial class UserControl1 : UserControl
{
    public UserControl1()
    {
        InitializeComponent();
    }
 private void Humeruslinks_MouseEnter(object sender, MouseEventArgs e)
    {
        HighlightOA.Visibility = Visibility.Visible;
    }

    private void Humeruslinks_MouseLeave(object sender, MouseEventArgs e)
    {
        HighlightOA.Visibility = Visibility.Collapsed;
    }

Xaml:

<UserControl x:Class="TestWPFApplication.UserControl1"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

The whole thing works fine when I create a brand new WPF-project, no problem at all. The thing is, when i try to include the usercontrol in my existing WPF-Project the paths go all over the place. See here (only the colored in areas on the picture)

I tried it in blend and vs, each of them 19 and 22. Tried to make a new usercontrol in the existing project and to import the one i made in the new project. I even converted all the paths to each absolut and relativ format. Always the same result. Now I am kind of losing my mind.

csproj-file:

<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop">
<PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net5.0-windows</TargetFramework>
    <UseWpf>true</UseWpf>

  </None>
  <None Update="appsettings.Production.json">

  </None>
</ItemGroup>

Does anyone of you have an idea how i can solve the problem? Does maybe any of the nugets interact weirdly with paths or a canvas?

Thanks rfmodulator,

Old code laying around was absolutly the right hint. Had an old path-style in a resource-dict, that cost me an entire weekend...

<Style TargetType="{x:Type Path}">
    <Setter Property="Fill" Value="Gray"/>
    <Setter Property="Width" Value="15"/>
    <Setter Property="Stretch" Value="Uniform"/>
</Style>

No key so it messed everything up. BooleanToVisibilityConverter will be set up as well. Thanks so much!!
