Bevel modifier not working properly I have an object on which I want to apply a bevel modifier. After applying, no matter how high I increase the Width, the bevel stays the same.

About the object: 


I've imported a .svg and then converted it to 'Mesh from Curve'
In Edit Mode: Select all Faces → Mesh → Faces → Beautify Fill
Select all Faces → Mesh → Delete → Limited Dissolve
Then I extruded the Object and now I want to create a bevel


You can get the .blend file here.

What I want to achieve is this:



Anyone an Idea?
The 'Clamp Overlap' option is enabled on the modifier. Un-check this to have a bigger bevel.

I would then suggest immediately setting the bevel back to 0 as the current value will be very large.

Use Shift while dragging on the bevel width value to increase the value slowly.
