PGYTECH ND Filter Advanced vs Professional

[Blazino]

A little help here. I found a website the sells the PGYTECH ND Filter Set (ND 8, 16, 32, 64) for the Mavic 2 Zoom, but they have two different. One is the Advanced version and the other is the Professional version. Unfortunately, the site does not give any description on the two. I went onto the PGYTECH site, but they only have information what it appears to be the professional version. Have anyone tried both version out and can explain what's the different in the two. Thanks in advance. Links Below:

I guess you could use the CONTACT option of the PGY site to ask?
