i've just notice that the Currency symbol is behind the amount in timeline layout, changing the position in the configuration have no effect on this, please take a look.
That's strange. It should respect the position you set in Configuration of Events Booking. I remember it had that bug when I first released version 1.7.1 but I fixed it after that (about one or two weeks ago). So maybe you should download latest version from My Downloads section, upgrade it to your site and then check it again ?
