My guess is you have two separate sketches (look in Item side panel). Shapr3D allows coplanar sketches. There are several suggestions in this forum. Here is one:

The problem is it’s still combine sketches in some cases then you hit “Sketch (+)” button.
So I recommend always explicitly select needed sketch before continue working on it. That will save you from this kind of troubles.
