STM32CubeMonitor-RF 2.19.0 not sending ACI_GATT_CONFIRM_INDICATION after receiving indication

I have a characteristic that supports write and indicate. A command is written to the char, the server responds by indicating the characteristic to the client. 

I'm using Stm32CubeMonitor-RF 2.19.0 to test the server, but indications always cause a ACI_GATT_PROC_TIMEOUT_EVENT because STM32CubeMonitor-RF does not issue a ACI_GATT_CONFIRM_INDICATION after an indication is received.
