In extensions_additional.conf under both [macro-toggle-del-agent] and [macro-toggle-add-agent] AMPUSER is misspelled as AMPUSUER
exten => s,n,Set(CALLBACKNUM=${AMPUSUER})
[macro-toggle-del-agent]
include => macro-toggle-del-agent-custom
exten => s,1,Wait(1)
exten => s,n,Macro(user-callerid,SKIPTTL,)
exten => s,n,Set(CALLBACKNUM=${AMPUSUER})
exten => s,n,RemoveQueueMember(${QUEUENO},Local/${CALLBACKNUM}@from-queue/n)
exten => s,n,RemoveQueueMember(${QUEUENO},Local/${CALLBACKNUM}@from-internal/n)
exten => s,n,UserEvent(RefreshQueue)
exten => s,n,MacroExit()
; end of [macro-toggle-del-agent]
[macro-toggle-add-agent]
include => macro-toggle-add-agent-custom
exten => s,1,Wait(1)
exten => s,n,Macro(user-callerid,SKIPTTL,)
exten => s,n,Set(CALLBACKNUM=${AMPUSUER})
exten => s,n,AddQueueMember(${QUEUENO},Local/${CALLBACKNUM}@from-queue/n)
exten => s,n,UserEvent(AgentLogin,Agent: ${CALLBACKNUM})
exten => s,n,MacroExit()
; end of [macro-toggle-add-agent]
Sorry, but I don't know where these modules get generated so I can only point to where the typo is in the extensions_additional.conf
