Describe the bug

When using the review system (tap the "eye" in the lesson menu), numbers with multiple digits are displayed one above the other, but should be displayed side by side, i.e. 60 rather than 6 0

Steps to reproduce

1. Go to the main menu
2. Click on the left button with an "eye" icon under the 数字 十一到一百 text
3. Tap the green arrow at the bottom to progress until you see "6 0"
4. Observe the incorrect formatting of 6 above the 0, and not side by side.

Expected behavior

6 and 0 should be displayed side by side
