Cannot find certain array block

[xev]

Hi, I found an old post (2016) related to the project I am handling. However, looking at the block, I am missing one of the Array block.

It is the block connected to the Read Data [Channel] Block signal output. 

Don't know if it has been changed icon wise or just missing. Would appreciate an assist. Thanks.

It is 'Index Array' for a 2-D array. The icon in the palette is only for 1-D array. It changes if you connect a 2-D array to it.
