Unexpected character (symbol) in output

[abnova]

I have noticed an unexpected dollar sign character (symbol) in the output of several plspm objects (essentially, a single object [inner model], I guess). The character appears before each block's name of an inner model and it is inconsistent with the rest of the package's output. Affected objects are: an object of class plspm and its element inner_model. For example (see Value, Satisfaction, Loyalty):
