@gareth, the biggest issue for me was the fact that empty `calculate` fields in a form were set to `0` per default. The other is that calculate fields inside a group do not even exist, if the group is not triggered. ---

> [@raf](#): > > empty `calculate` fields in a form were set to `0` per default Yes, this is fixed in 4.0.0 ([tracking issue](https://github.com/medic/cht-core/issues/7222)). > [@raf](#): > > calculate fields inside a group do not even exist, if the group is not triggered I’m not sure about this one. Possibly it was tracked by [this issue](https://github.com/medic/cht-core/issues/4132)? ---

@gkesh did we use this version for our recent implementations ? We noticed the sync was much slower in comparison to the previous version. Please check in with teams here cc @nitin @niraj @gaarimasharma
