Sketch - already has same dimension on referenced geometry

[mbraga0001]

The red mark below show the area of interest. I defined a dimension (angle) between these 2 lines but it disapeared.

When I try to re-add the dimension again I receive an error message: already has same dimension on referenced geometry.

Is there any other way I can see the dimensions, constraints so I can fix this ? Thank you.

Solved with information provided by TheCADWhisperer.

The Modify / Change Parameters is the "other way" to access the constrain parameters.
