Gruffudd Maelor ap Madog, Lord of Bromfield - Escutcheon (shield)

For clarity, this Gruffudd ap MADOG, born circa 1130 could receive the suffix designation 'I' to distinguish him from his grandson Gruffudd ap MADOG II born circa 1195. The red striped escutcheon attached to Gruffudd II is Coat_of_arms_of_Gruffydd_Maelor_I_ap_Madog_Prince_of_Powys_Fadog, which differs from the stripeless shield of the prince between these Gruffudds. The file name is incorrect or the shield is attached to the wrong Gruffudd. Who can shed light?
(Note: an escutcheon emblazoned on a shield is the focal center of a Coat of Arms, most often surrounded by a floral design and/or upright animals, and topped by a crest.)
