How to hide FLEX fields on Redwood Goals Center page?

Summary:

Since upgrading to Redwood, we have found 3 FLEX field in Me→Career and Performance→Goal Center which weren't there
previously.

In Me->Goal Center, on the Goal Details section, the fields are

_FLEX_ValidationDate
_FLEX_NumOfSegments
_FLEX_NumOfVisibleSegments

In Visual Builder, I cannot see these fields available to be hidden.

I've checked Descriptive Flexfields, and none of the following have any attributes defined:

HRG_GOALS
HRG_GOAL_PLANS_B
HRG_GOAL_ACCESS

Anyone else seing this? How can we hide these fields?
