Export as .jpg issues in Luminar 4

I've just done the latest Luminar 4 update 4.1.0 and still find that exporting more than 1 image at a time results in incorrect colors being processed (it was a jpeg).  I exported 3 only as a test and it is extremely slow and the colors are not the same as the processed image in Luminar.  When I exported one at a time and waited the 10 to 15 seconds that it takes for the adjusted image to fully open with the correct colors then exported it was fine.  I'm thinking that due to the length of time Luminar takes to open a raw image, compared to other applications (Lightroom, On1, Photoshop etc.)  that if we export a number of images at the same time it is exporting them before they fully open and with the weird colors that appear before it is fully open. 

So far I'm extremely disappointed in Luminar, since early days we've been told about the lightning fast processing and this is so far from reality.  There are features that are good but until it can process images quickly it is quite a useless application.  I found other closed posts on this problem but could not find any answers.  When will this be resolved?   Heather
