New Bug Encountered in expression assistant

[Stephane_Liema]

I’m creating a new application, and i’ve got this error message

ORDERBY(SELECT(System[Sys_Label],AND([Sys_Type]=‘TYPEFICHE’,[Sys_Actif_B]=true),true), [Sys_Tri])

In table System the column Sys_Tri is present

AppSheet knows this colum because it is displayed :

What is strange is there is no error for this expression

No error for the Sys_Label column, So AppSheet knows the column Sys_Label

And when i add the Order By clause with this column

ORDERBY(SELECT(System[Sys_Label],AND([Sys_Type]=‘TYPEFICHE’,[Sys_Actif_B]=true),true),[Sys_Label])

I’ve got the error message !!
