Cannot create a risk

[Fabrica_AE]

We are trying to add a Risk into a Business process diagram, a new pop-up appears , and we typed the name of that risk, and apparently it does the process, but the risk doesn't appear in the diagram , for example, we create the risk called "risktest"(image1), apparently it does the process of add it, but the element risktest doesn't appear in the diagram(image2), even if we try to search that element, it doesn't appear.(image3) What could be the situation here? I'm attaching 4 images here, the 3 first are related to that situation I'm saying, the last one is a view of the log, also I'm attaching the log if is needed. Thanks for your help.
