R545 - Custom profile can't set to fixed

[HeiWoMa]

I have build a Custom columns called "hwm" and set width for the column/Tile "Name" to 45.
- Open Tab1 -> Menu: View -> Column profiles -> hwm --> the column Name looks fine
- Open Tab2 -> Menu: View -> Column profiles -> hwm --> the column Name looks fine
- In Tab2 resize the column Name with mouse
- Open Tab1 the column Name is resized to the width set in Tab2
- edit "hwm" and see that the width for the column/Tile "Name" is set to e.g. 20 (width from Tab2).
This is not good. It should be possible to set a Custom profile to fixed. Changes in Tab2 should have no influence on Tab1 and also not change the profile.
