I've had similar on mine, I just pinch out the damaged bits and it doesn't seem to impact on the rest of the plants. Had some plants really damaged a few years ago and they came back fine the following year.
Thanks @lilybee There are some buds. I will see how the flowers are. I took this plant from a cutting from my neighbour last year. It was the first time I was ever successful taking cuttings from fuchsias. But I have 3 more cuttings that were successful this year. Two rooted in water and the other one straight into compost
