The horizontal label is fine, it says Pon S in all images. (I guess a wrong label would be obvious to detect for specialists.)

The problem are the vertical labels

In Figure 1e it says: "MT1+2", "MT2" and "MT1"

In Figure 3a it says: "5'-CR1", "CR2" and "3'-UTR"

In Figure 3b it says: "CR2", "CR3" and "CR4"
