Issue with price on website displaying as 0 or wrong

Hi. We are experiencing an issue with our prices on the website. We are using the WOOCS currency switcher and it seems like its causing an issue with the pricing that is shown on products, the price will appear as either 0 or it will show odd pricing when switched to different currencies. We are displaying the price two places on the product one at the top for noticeability and one at the bottom to show the price and the price ex. VAT. I have been trouble-shooting to find the issue and when disabling plugins it seems WOOCS Currency switcher and Woocommerce pricing are clashing in some way. It would be great with some assistance to how we can fix this issue.
