Commands changed after snapshot

The chain of commands I have in the picture once executed something every 5 seconds.
After I updated to 17w16a it executed constantly

I had to change the second repeat block to be the third (from fourth) block in the chain. The commands past that repeat block also execute 3-4 times for no reason

R AA: /scoreboard players add Name NameofScore 1
C AA: /scoreboard players test Name NameofScore 100
R C AA: /scoreboard players reset Name NameofScore
C C AA:/scoreboard players set @e[tag=!Name] NameofSecondScore 1

It used to be
R AA
C AA
C C AA
R C AA and it worked fine
