The exported table you shared has not been rarefied at an even depth, and 13A has the highest number of sequences. So it is not comparable to the alpha rarefaction plot you shared, which displays the number of OTUs observed at each sampling depth. It also looks like there are only 140-some OTUs in the table, so it seems like you are comparing data at different processing stages (e.g., ASVs vs. OTUs? Pre- vs. post-filtering?).
