Sorting filter in frontend doesn't work properly

I've noticed that sorting by the most recent doesn't work well. Also, when you select a filter there is no indicator that it is being processed and this causes confusion. To reproduce: 1. Go to "https://meta.decidim.org/processes/bug-report/f/210/" 2. Select "Order proposals by most recent". 3. Scroll down and you will see a proposal created today among older ones. Take a look at the attached gif.
