Total Finder won't copy more than 128 items?

I’m trying to copy 1121 files over a network share to my mac.
I highlight all the files… drag them to another window and the copy dialog comes up saying copying 128 items. I’ve tried it 4 times in a row, and it just seems to refuse to copy more than 128 items at a time. I’m on Mavericks with Total Finder 1.6.17.
