auto generation of docString of PY functions broken?

2019.3CE PyCharm (windows)

Please, am I alone experiencing either different or erroneous behaviour of docstring autocreated by Pycharm in this latest version? I mean:

def function(a,b):
    (here, type quotataion mark 3x) - usual result was it expanded to """""" with a cursor inbetween.
Then I pressed enter and got something like
def function(a,b):
    """
    :param a:
    :param b:
    :param c:
    :return:
    """

however after this update, these param and return rows are... missing, they just don't appear. At all. Am I alone, please? Am I missing something?
