Rule Engine MATCHES function

I have column “备注” with values like this

1/9 首存2选1首存彩金

1/9幸运注单福利派送

1/10 每日电竞签到

1/10周周投注周周送8倍

01/02周周存周周送

02/16活动3CH直客日存活动日存礼金

11/26日王者归来活动一8倍

12/13活动二Hiwallet笔笔送

28 2/22活动三小9直播日存，

38维护彩金 彩金6倍

42.91.166.79

then I used this expression $备注$ MATCHES “^\d{1,2}/\d{1,2}.*” => TRUE but it does not show any value, what is the correct expression for this?

thanks
