Buggy filter buttons

Not exactly sure how I ended up in this state but I will try my best:

1. After installing the app I set the filter to sport and a grade range from 6a to 7b+

2. I cleared the filters

3. Pressing a filter button on the map brings back the grade range.

Further testing:

1. I set a completely different grade range and a boulder filter on the filter sheet

2. Apply

3. Turn off the boulder filter from the map button

4. Turn on the boulder filter from the map button

5. When opening the filter sheet, my initial grade range (6a to 7b+) is set again.
