Is this a bug?

 

While at cruise altitude (most likely also at other stages). Click DES to go to DES page. Click CLB (one time), you will get to CRZ page. Click CLB (second time) will get to CLB page.

Probably! Thanks for reporting!

I did some testing.

It looks like this is only happening after reaching cruise altitude and annunciator changes from CLB to CRZ.

Before reaching the cruise altitude (while in climb mode CLB), the CLB button on the CDU goes to CLB after first (single) click.
