ReplaceRegEx failing in AttributeManager

Hi all,

I'm trying to clean latlongs using RegEx in the AttributeManager but I'm getting below error.

AttributeManager_2: Expected signature @ReplaceRegEx(UTF8,UTF8,UTF8,[BOOL]) but received ReplaceRegEx("latitude" content="52.132932,("latitude" content=)

Feature Type: `AttributeManager_OUTPUT'

Attribute(encoded: UTF-8): `LAT' has value `"latitude" content="52.132932'

Attribute(string) : `fme_feature_type' has value `Creator'

Attribute(string) : `fme_geometry' has value `fme_undefined'

Attribute(string) : `fme_type' has value `fme_no_geom'

Coordinate System: `'

Geometry Type: IFMENull
