Path Recommendation for 50 y.o. male in US

[ill13]

I'm on the final touchstone for "Intro to Psychology" I've submitted 2 of 3 touchstones for this course within the last 3 hours. 

I can likely finish the third and final within the next hour. [I like to talk and write!]

Is this a problem / error with Sophia?

I was under the impression I could only have 2 touchstones active at any time?

...Or does the '2 touchstone' thing only apply to two different courses?

I.e., any single course, any number of touchstones per course but a LIMIT of 2 courses with any number of active / submitted but ungraded touchstones?
