'Suggested locations' shows incorrect capacity

PeterRising Found this https://office365itpros.com/2019/08/28/populating-locations-outlook-places-service/ and in the comments below, reply 6, another person has the exact same issue. I believe I'm gonna follow Mr Redmonds advice (support case). Thanks for your reply Peter, appreciate it. Btw, really impressed by your contributions here. Great skills!

*updated* partial solution is to clear the cache in Outlook on the web (e.g. hit "x" on the suggested location) as the Outlook client populates it from there. Still no explanation why this is happening or how to solve it org. wide.

*updated* final answer from Microsoft premier support

"There is no way we can clear the suggested locations for all the users. I would like to inform you that it is not necessary that all the users are facing this issue. Users which have used this room in the past must be getting it as suggestion. There is no way we can remove the cached location for all the mailboxes from admin center or by running any power shell command."
