GPT - S1 Slice Assembly with polarimetric matrix generation

Splitting the graph does not seem to solve the issue.

I think it is related to this problem, because I cannot perform slice assembly before performing the deburst operation on one hand.

On the other hand, the final output displayed does not show the slice-assembled result, but only one of the two slices, which is akin to the following issue:

Therefore, is there a fix to the problem?
This is the result I get by performing a gdal_merge or a SAR-Mosaic operation after applying the graph from my previous post to the separate slices (without assembling them).

If I include Slice Assembly and split the process into two graphs like @lveci suggested, the output only gives the bottom(or top depending on order of files provided to the ProductSet-Reader) half of the figure shown.
