[Eco Bounty] IoTexScan Missing Spacing in Chart Title

Description: On the Staking Ratio History chart page, the primary heading of the chart container is displayed as a single string of text without spaces ("StakingRatioHistory"). This contrasts with the breadcrumb navigation above it, which correctly displays "STAKING RATIO HISTORY".

Steps to Reproduce:

1. Navigate to the IoTeXScan website.

2. Go to the "Charts & Stats" section.

3. Select "Staking Ratio History".

4. Observe the white title text directly above the chart timeframe selectors (5D, 1M, etc.).

Expected Result: The title should be formatted with proper spacing for readability, e.g., "Staking Ratio History".

Actual Result: The title is displayed as "StakingRatioHistory".
