Hi. This is a reported issue with 24.2 when the calculated field expression contains additional characters other than xxxxxx^xxxxxx (example, acpinv^chknum). We will be addressing this in a near future update. As a workaround, you can delete and replace the field using one of the standard or global calculated fields for company name in the system. See Knowledgebase article 117313 for details. Also, articles 88039 and 44329 provide additional instructions for global calculated fields.
