Propagated route issue on AWS VPN

Question

I have successfully created a site-to-site VPN to AWS with my on-premises VPN box, while testing route propagation, I found that some of the propagated routes on the VPC route table are missing, does anyone know what the problem is?

Answer

Current quota for Dynamic routes advertised from a customer gateway device to a Site-to-Site VPN connection on a virtual private gateway is 100 routes, Is the CGW advertising more than 100 routes by any chance? If that is the case only solution would be to summarize the routes.
