Can't see my EC2 instances on the management console?

I'm a beginner to AWS and servers in general

I logged into AWS on laptop 1 and set up an EC2 instance. Next day I logged into AWS console on laptop 2, then the instance was gone. So I set up another EC2 instance to play with. Then logging into the console using a third laptop 3 the day after that, I found my first instance but not the second...

The second instance is still running as I can access the IP..

Any idea why this is happening? It's really confusing and annoying

Thanks!
