Issues with the M10 bracket in the standard pipe rack drawings

It’s strange here: M2 has only one page; there are no M2-1 or M2-2 versions. Moreover, M2 comes in only three series numbers – 10, 15, and 20 – while numbers from 25 to 65 are available under M3 ； Type II is DN80~1000, corresponding to drawing numbers M3-1,2,3,4. Like the M2, the M3 also has only one page, with series numbers of 25, 40, 50, 65; those above 80 are M4. Is the album wrong here? There’s another issue: the diagram shows stoppers, but there are no part numbers indicated, and they’re not listed in the material table below. Do we not need to consider them?
If you are familiar with this atlas, based on the criteria for errors, should M10 type II use M5–M8, or should M4 be considered?
Obviously, there is indeed a mistake! The poster can refer to the atlas “05S9 Pipe Supports and Hangers” for comparison
