Why can’t I configure the GTS PMA/FEC Direct PHY IP into Internal serial loopback mode when the Transceiver RX Adaptation mode is set to manual mode?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a problem in the Quartus® Prime Pro Edition Software version 24.2, when the RX adaptation mode is set to manual, you cannot enable the internal serial loopback feature, as this will cause functional failure of the GTS transceiver. 

Resolution
