Describe the bug
the width of bottom 'all' tab under the 'all' section is inconsistent; when you first open your bags, it is the same width as all other bottom tabs "all, normal, trade, quiver", but if you change to another section (like Equipment) and then go back, the width of the bottom 'all' button changes.

To Reproduce
Steps to reproduce the behavior:

1. Open bags
2. Observe the width of the bottom 'all' button, which is same as other bottom button widths. (see first screenshot, area with screen square highlighted)
3. Click on the 'equipment' section and then back to 'all' section
4. Observe the width of the bottom 'all' button, which is now smaller. (see second screenshot)

You can also recreate this by opening your bags, and then clicking the top-left 'all' button again, and notice the bottom tab changes size.

Expected behavior
The width should be consistent.
