After end countdown timer on product page not return regular price.

Hello.
I used the free version of the plugin and everything worked correctly. If I set a sale and a timer on the product page, then when the timer ended, the regular price of the product was returned. But it was not possible to set a timer on a bundled item. After installing the paid version plugin, bundled item it started working. But now, at the end of the timer, the regular price returns, after which the page automatically reloads and the discounted price is displayed. It is very uncomfortable. At the end of the promotion, change the price to the regular one manually. How to solve this problem?
