I noticed the following last night. I've tried it using Firefox, Chrome and Opera GX (all desktop) and the results were the same, so not an issue my end.
I've also tried it using Google.com as well as Google.co.uk - no difference.
Without quotation marks, Google the following and look at the names underneath.
"star trek tng family cast"
I've no idea what's caused it.
