Dear, I encountered a problem with the price filter. From an Android smartphone it is not possible to use the selector but only to enter the amount by typing the price in the field.

In any case, both from a smartphone and a PC, if I select the maximum price without selecting the minimum price, the selection does not give the desired result but the items with prices higher than the selected amount are also displayed.

Only by setting even the minimum price, the filter works correctly.

I would like to point out that some items have a ZERO price.

It would be interesting to add the possibility, in the case of products where you do not want to set the price, that the purchase button becomes a button for requesting information. See for example Virtuemart.

Thank you! I await your solution to the problem.
