Upgraded to CB1.8

We currently upgraded to CB1.8 and did core CB db check from the tools and discovered an error:

Warning: 368 entries in Community Builder comprofiler_field_values link back to fields of wrong fieldtype.

fieldvalueid=605 fieldtype=text

fieldvalueid=606 fieldtype=text...

We actually coud not find solution for this.
Does this cause critical risk by leaving this error?

That was most likely there before the upgrade.

Problem is that you have values in the comprofile_field_values table that link to cb fields you created that do not support value selection.

Did you or someone else edit the database and make changes?
