grouping makes appear pseudo participants

Question

Hello , 

Here is my sequence diragram : http://www.plantuml.com/plantuml/uml/ZOunoiCm38LtdUBXDUG26VxXBtWkc1p0JToInGwoMdhyOaKG6Z8qa_A-9-kBanJ6M1CZLenqAs-4_ykLriYoJCiQiy3vXQkurl3V8AIfv5b981hH_y430roLoEA87boUA-vjNqS2W5maeRmI7u1-SGktbgOfp_kFRpS2kWw35JKEThhlCUY2iJPkxvjALUCJ5oC76Kj_aB7YkOt1NUS3

I 've just tried to make 2 request / repsonse groups.

each made appear a strange unwanted participant (firstgroup and secondgroup).

is there a way to remove them  ? 

Of course I export and edit a png but would be more convenient to have a clean diagram directly.

thnaks for your help
