Can't insert way points B787 FMC

I was trying to insert a way point in my flight plan but it was not recognized so I had to fly the initial route.

In other flight, I input the wrong way point (it had the same name), but was impossible to delete or just replace it with the next way point.

Am I doing something wrong or is it just a bug?

second one is a bug. First one may just be missing nav data.

Sounds like a bug. Be sure to report it to Zendesk - I reported a similar one within the 787 fmc and hopefully some changes can be pushed with patch #2.

Thanks! I will check that out.

Thanks. I will report it. And, yes, I am waiting for that second patch.
