I have came across this while customizing the Dawn Theme filter, Drawer Style. ( I tried with the original code too , same error)
To replicate:
Step 1: add a prince range EG 50 to 100
Step 2: go to another list type filter and select at least 3 options at the same time
Result: The price range will change. PS the more filters you add, the range will keep up getting bigger until it resets.
Am I the only one?
Thanks!
