Double write in SigmaStudio 4.1

I am working on a project with ADAU1761.

By some reason when changing some parameters in SigmaStudio 4.1, the capture window shows that data is written twice - same data to the same addresses. It happens with the invert cell and with equalizer, for example. When equalizer slider changes position, the capture window shows that safeload write of 5 words takes place, and then the same exactly safeload write is repeated.

I don't see any reason for this. Is it a bug in a SigmaStudio 4.1 or it's really necessary?   

Thank you,
