How do I un-retweet old RTs that don't show the green arrow?

[Stephi]

Hiii! I'm trying to clean up my Twitter. I've had it since early June and I have 880+ followers. I used to fangirl over this teenybopper actor who I don't even like anymore because he's a narcissistic jerk.. and I had friends who were crazy for him, too. Unfortunately, I retweeted a lot of stupid tweets about him, and photos. But now, when I go waaay back into my early tweets starting August 5th and late September, my friends' tweets are on my profile but I don't have the option of un-retweeting them. In fact, they don't even have the little green arrow that indicates that I retweeted them. It does say in the small grey letters, "retweeted by" (my name) at the bottom. but where "Retweeted" should be, underlined, it just says "retweet" but I already did!!!! so I have the option of retweeting it. This is on MY profile, not the timeline. I want to remove them!!! How can I get these stupid tweets off my profile for good?

I'm having the EXACT same problem. I've tried everything and have not yet found a way to delete them... I will keep you posted however, if I eventually do!
