Stair components are not continuously connected

[jagostinho74]

When editing the sketch of a stair by component the "Stair components are not continuously connected" warning emerges after the stair is changed from straight risers to arched ones.

Is this due to the use of arched risers or is it something else?

See file attached with two stairs, one without warnings (straight risers) and the other with arched risers (with warning).

I've opened your file. But all the risers are straight, except for the top one.

After changing all the riseres to arched risers, I didn't get any warnings (Revit 2016). For me it works fine, but maybe you're trying to do something different.
