Price Filter doesn't Change Currency

Hi there,
After adding a second group of currencies (ZAR) to my woocommerce store using this plugin, the price filter remains unchanged. The currency symbol does change to South African Rands, however, the actual values remain set at the USD numbers.

Items in my store range from USD29-USD79. After adding the new currency, products in the main page are now correctly displaying as ZAR350 – ZAR1050, however, the price filter shows a range of ZAR29-ZAR79 (The USD figures).

Any ideas how to correct this?
