Merged Swaths don't recognize Vector

I have two swaths I have merged together. The Vector file I’m targeting can be imported into the individual swaths, but after they are merged, I am getting an error, “The vector data was loaded successfully, but no part is located within the scene boundaries.” Why would that be? Here are the two swaths and the merged in linked windows,

I’ve done this successfully in the scene to the north.

[Solution] I wanted to have this to subset the merged product, but I didn’t know that the subset tool automatically zooms to the window you’re viewing. Once it was subset and I ran Multilook, I was able to import the vector file.
