Deleted Message shows up in Activity > Feed

Hi community,

While using Team and messaging in a channel, post a message which was not intended for the channel, so deleted the message. Even though it got deleted from the channel chat window, the channel members were able to see a the first line of the chat in the Activity > Feed window (although on selecting the feed entry it shows the message was deleted).

is there a way where i can stop this from happening? If i delete the chat, it can retain the activity in the feed but not show the chat text as a preview.
