chore: React warning fixes

[RMCampos]

Description

TL;DR;

• Fixes warnings when running locally.

Full description

Stopped to look at the charts, understanding why they don't have data locally. Here's why:

• When we started using the real backend locally, instead of test, no data was fetched from Oracle. In simple words, there's no data locally to be displayed.
• But when looking into that, some warnings could be noticed. This PR aims on fixing them

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Tested locally,
