Description
In the latest specification, in part 8.4.4.2 (Derivation process for motion vectors and reference indices in subblock merge mode), the 8th point precises that zero affine models are added at the end of the list as:
– The candidate zeroCandm with m equal to (numCurrMergeCand − numOrigMergeCand) is added at the end of subblockMergeCandList and numCurrMergeCand is incremented by 1
But in the current implementation, numCurrMergeCand is not incremented.

Note: See TracTickets for help on using tickets.
It needs to be incremented every time a candidate is added to index the subblockMergeCanList properly.
If there is an issue, it might be a VTM one.
