Destination Change when nearing destination

Hi there!
Sorry if I posted this in the wrong topic room…
I’ve been using the Navigraph Hub and Simbrief integration for my navigation in MSFS 2024. However, whenever I am nearing the destination, my co-pilot would request for Destination Change and then after that I am stuck in a “loop”. The tower requesting for my acknowledgement while I could only answer “Say again”.
Had I missed something when using the Simbrief EFB? Please help, thanks!
