You have had a screen done at some point and the bloke has bent the rubbers up rather than remove the whole thing, most likely to save on clips.
The bend on the front is a give away.
Get a big bag of clips of the net and do the lot, try and get the kink out as well
The little posts the clips clip onto tend to rust quickly and creep up onto the roof, can be a proper rust trap under the rubbers good luck
