Sogo duplicate email in sent folder

Sgo Versione 2.0.0
Hi everyone, although I tried to change the exclusion of the sent iterms folder on imasync, when I send an email from SOGO only in sent mail it is duplicated.

I tried among the many options, deactivating activesync from my phone… nothing to do, if I send an email after a few minutes I find it double in sent items
