Effects not found

I’ve not had the pedal long but seems great. I noticed a ?problem the other day. I had synchronised my project with the pedal. Went and used the pedal ok. Next day altered some songs…exported, imported all ok, saved project. The when I tried to synchronise again I got a lot of messages “…effect xyz etc” not found. This happened for I guess a dozen or so times during the synch, each time I continued until synch completed. It did not happen the first time I synched. The pedal seems to operate normally and has the new stuff on it. Have I missed something? Ive checked the manual again but can’t find an appropriate reference.

I’ll investigate this issue. I remember I read about such problems already.

Thanks Daef…the pedal seems ok, but I was curious
