Start and End Value Reset

Hello – I am trying to place the counter widget in the footer of my site and whenever I save it, the Start and End Values reset to either 0 or 100. Any guidance on this? I’m trying to do a continuous counter, but have tried it as both continuous and non. I have updated the number of digits to 6 (my end value is 450,000) and tried a few different starting values (0, 300,000, 350,000) and none of them seem to stay. I have also adjusted the counter speed from 5 to 20 to 50 and that seems to make no difference either.
Thanks for your help!
