Getting Woodland-Druid from Neeko after removing her

I started off my game by building Woodland-Druid with Maokai, Leblanc, Ivern, and Neeko. I later removed the Neeko and Ivern to replace them with new heroes, and I noticed I still had the Woodland and Druid buffs. When I hovered over the origins on the left side, Neeko was highlighted as if she was still part of my team. I was still getting the healing buff from Druid and the copy from Woodland. The only time I didn't get a Woodland copy was when my Maokai was banished by Zephyr, which might be intentional.
