Lightroom to Photolab 5 Elite to Lightroom - Temperature shift

Is anyone else experiencing this or similar? Using Sony RAW files from Lightroom I use File/Plugin Extras/Transfer to Photolab 5. In PL5 I use lens corrections and Noise reduction only before exporting back to Lightroom. Back in Lightroom there is a distinct ‘warming’ of the image and the histogram is shifted to the right. Irritating. Is it something others have experienced or am I doing something daft?

Thanks

Yes, my RAW-Files of a Panasonic camera (MFT) also are significant warmer in PL5 than in Lightroom.
