Parameters not being used

[olfZMZA6]

There is a bug where the parameters created are not being used!

How to recreate:

1. Create a box (e.g. 20x20x20 mm) (which plane doesn't matter)
2. Create two parameters:
   1. name: low, unit: none, Expression: 0.2
   2. name: high, unit: none, Expression: 0.8
3. Select Filet tool
   1. Select one edge (anyone, but just one) on the cube
   2. Set Radius Type to Variabel
   3. Corner Type: Setback
   4. Click two random places on the selected edge to create Point 1 and Point 2
   5. Start: 3 mm    0.00
   6. Point 1: 1 mm    low
   7. Point 2: 1 mm    high
   8. End: 3 mm   1

This creates this image before pressing ok - everything is still fine:

1. Click OK
2. Change parameters:
   1. Set low to 0.3
   2. Set high to 0.7
   3. Click OK
3. Note how the figure doesn't change shape.
4. Edit the Filet Feature and notice that the variable names have been changed to fixed figures - the original figures.
