Hi! I made similar post back then, when 1.16 fame out.
OcelotOnesie [moderator] already commented here on that. But I have not indeed mentioned structure blocks, just commands and cloning. So if You mind, You could add additional details about about Your experiences with structure blocks to my original post (MCPE-89393) and even consider upvote!
I am really glad that I am not the only one that notieced this behavior, I am really sad that it is not working as expected :/
Have a nice day!

It's extremely big shame, that such a big studio as Mojang is UNABLE to fix this microscopically-easy issue. It's literally changing a number in text editor (_)

Here is the bug itself:

And here is the tested enviroment: 

https://www.reddit.com/r/Minecraft/comments/f2wf12/bedrock_i_made_a_mob_transportation_water_line_25/?utm_medium=android_app&utm_source=share

But I've found out, what special curcomstance caused this issue, but it sill need to be fixed, but not as urgently.

I've summoned the zombies via commands, but I've used the Mob event. Bud not finished. First time, I was testing it only with baby variants (because that's what is it made for), and, because I am lazy and I know from the past, that if I do not delete the whole spawn event (f.e.: minecraft:as_baby), just one letter or something, that it will spawn adult variants of the mob. So my final command looked exactly like: summon zombie -117 26 1246 minecraft:as_ba

So it spawned as usually adult zombie, but it was broken for some reason. After further testing, I know that mobs spawned naturally or with spawneggs or properly via commands (/command blocks) are behaving as they should. This strange glitch occurs only when you spawn adult version via commands with unfinished mobevent. At least that's what I've found out. Thanks.
