The problem is that they use the correlation coefficient and its
standard error directly which does not guarantee that the confidence
limits fall into [-1, 1].
A better approach is to use Fisher's z transformation and to
back-transform the results (with CI limits within the admissible range).
This is the default in metacor() of R package meta. You can also use
rma(..., measure = "ZCOR") in metafor, however, have to back-transform
