SMA Declarative Page Cache Management in 7.1.9

In 7.1.5 I used to be able to click Advanced > Declarative Page Cache Management > Node Pages: Clear and this would clear all node level pages on a node.

In 7.1.9 I try this and I am given this:

When I select a node page key (of which there are more than 100) I get this:

The desired behavior is to click Advanced > Declarative Page Cache Management > Node Pages: Clear and have these rows show 0:

Number of Node Pages
Total Node Page Size

The alternative for us is to open each D_xx data page on each node, click Load Management, then click Clear Data Page. Because we have 8 nodes and 3 data pages per node this take a lot of time; if we could just use SMA to clear all Node Level Pages as we did in 7.1.5 it would greatly help us.
