thanks for your quick answer. It may be normal behaviour, but I think that’s kind of error by design. A last element should get lastClass set, regardless if there are other elements - the first element can be the last element.
Have you any recommandations for me, how to deal with this? I could try to change the code, I did some php programming years ago, but I would run in problems with every update.
Should I try to contact the developer, so he could change it, or maybe provide a config option in the snippet’s call like oneChildOnlySetLastClass=true/false?
