Price getting removed when i import

I have the latest versions of wordpress woocommerce and this plugin but im still getting this problem.

Here is a sample of the CSV file im importing:
70,1.59,P759126
0.00,1.16,1212017
0.00,1.16,1212019
0.00,1.48,1212413
6.00,1.64,1212423

my header is set to:
stock; skip; sku;

i also have merge products set to yes in the settings, so in theory all it should be doing is looking for the SKU and updating the stock.

When i do an import the stock level gets updated however the price gets wiped out.
