Circular Sketch Patterns with Congifurations/Design Tables

In SW2017 have a design table driven part with multiple configurations.

One of the features is a series grooves on the inside of a spherical radius which is driven by a Circular Sketch Pattern.

The spacing angle between the grooves is driven by the design table and everything works fine, almost.

I've got 40+ configurations. In a small number of configurations the spacing angle doesn't get read from the design table.

Most of the time a series of rebuild, edit the table, save, close, reopen, rebuild again will get it to work after a while.

Anyone have any thoughts on what is happening, or if circular sketch patterns and design tables just don't work well together.
