Suppress by expression and unsuppress in UG Nx

Hello all,

In Ug Nx. I Couldn't able to unsuppress the feature which is already suppressed by expression.
for example.
Step-1
I was applied a radius in one edge of a block.
Step-2
That radius was suppressed by expression.
Step-3
I want to bring back the original feature. I used to make unsuppress the radius. But not suppressed.

Any one can help to me the Why the feature is not getting "Unsuppress" which is already suppressed by expression.

Thanks & Regards
