I have a Jenkins job, that deploys 16 lambdas.  When you add the 17th, you no longer can select Update mode.  In the chrome console you see the below error.

Uncaught TypeError: vg.rowVisibilityGroup.makeInnerVisisble is not a function

The only work around it to create a second job that only deploys the 17th and above lambdas.
