Incorrect NumInGroup count for repeating group

I am keeping receiving this error for validating the below message. The number is correct (268=8) which I can manually count. Could anyone show me the way to resolve this please? Thank you!

8=FIX.4.2 9=0485 35=W 34=1652 49=XYZ 52=20210901-09:48:20.444 56=xyz 262=ABCUSD 5000=0 109=abc 55=BTCUSD 268=8 269=0 270=47553.20 278=36 271=5.00000000 290=1 269=0 270=47550.20 278=32 271=7.00000000 290=2 269=0 270=47547.20 278=2 271=10.00000000 290=3 269=0 270=47544.20 278=102 271=50.00000000 290=4 269=1 270=47597.24 278=72 271=5.00000000 290=1 269=1 270=47600.24 278=81 271=7.00000000 290=2 269=1 270=47603.24 278=26 271=10.00000000 290=3 269=1 270=47606.24 278=50 271=50.00000000 290=4 10=102

But current validation works fine with this
