Speed Boost bug with Morgana

Earlier I had a match as Morgana Support.

Everytime I would land a Q or a W on an enemy champion I was getting a 1/2 second speed boost. The ghost walk icon would appear for 1/2 second everytime.

0-18-12 spec wanderer, secret stash, meditation, bandit, intelligence, windspeakers blessing unyeilding, explorer, runic armor, insight Items, Frost Queens, speed boots, ardent censor, sight stone, athene's grail

2nd match I was Morgana top but used a different spec and build and nothing happened.

3rd Match I was mid and decided to build her support again and I got same bug. But this time it did not work for a bit and then it did but I was getting the Liandry;s Icon to pop up and then it changed to Ghost walk.... Same talents... slightly different item build Items, Frost Queens, hexttech glp, speed boots, athenes grail, zeke's harbinger, rabadons cap

.. I filled out a bug report but I figured I would post it here too if some other people can replicate this bug.

I have a feeling it has to do with the spec and frostqueens....and maybe even possible teammates or enemies spec/build.
