ABCIP and array in Rockwell

Hi, I'm using system platform version 2020, with a PLC L84ES,

I am trying to read and write from an array in the PLC, unfortunately autobuild does not work, if I compile IO Device in manual everything works. All variables without array [ ] work correctly, what am I doing wrong?

In the watch table the syntax is the same, I can't figure out where the error is.

Tagname
OperationType.0.Meat.Load

Autobuild
<IODevice>.$RcpMixer.OperationType.0.Meat.Load

Tagname
OperationType.15.Meat.Load

Manualbuild
MyPC.MyPC_Medium.PLC_RcpMixer1.OperationType[15].Meat.Load
