Agilex 7 AGIB027R29A1E2VC board QSFP-DD issue

We have Agilex 7 AGIB027R29A1E2VC board which has two 8-channel QSFP-DD ports, both are connected to F-TILE Bank 12A. QSFP-DD Port B is connected to FGTL12A_Q2 & Q3, while QSFP-DD Port A is connected to FGTL12A_Q1 & Q0.

We have a QSFP-DD A port project (4 x50G PAM4 settings), we got error when compile it, as shown in the attached figure.  If I change the pin assignments for Port A to those of Port B in the .qsf file, the compilation succeeds without any issues. However, compiling with Port A's original pins fails. I'm not sure why it happened and how to fix it. 

Can anyone help check this issue? Thanks in advance!
