Hello,
I have a rollup of a linked field using the formula, ARRAYUNIQUE(ARRAYCOMPACT(values))
For all records which do not have a link, the rollup field is blank. When I group a view by this rollup field, most without the link used by the rollup are grouped by a blank value. For some, however, the rollup grouping’s value is (Empty). Any idea why this is happening?

Thanks!
