I've try to import ASCII PCB from altium designer into easyEDA pro to do the multi color silk screen PCB feature in easyEDA.

I've using altium designer version 24 to save the PCB file into ASCII file the import into easyEDA  version 2.1.64 (latest)

look like the all polyregion are missing.

but when I try to older version of eastEDA pro. 

look like version 2.1.59 was working fine.

I also try other version of altium designer to save the ASCII file. result remain the same.
