:memo: Implementation

• The problem manifested when the campaign name used special chars (in this case: (, and ) -> CV_BAORO (RCA) multiAg Sept/Nov 2022).
• Instead of building a matching regexp, it has been refactored to match the suffix directly by string.
• No changes are required in the DB, the teams were correctly stored, it's just the count get that was failing. (So it was safe to put the correct value and re-save)
