Representing increase/decrease at glance on "opposite" labels?

I'm building the front-view of a marketing Ad fraud analysis tool that wants shows users how much ad fraud vs valid traffic they get.

It already does this, and the purpose is to show at a glance in a clearer, faster manner.

The issue: an increase or decrease of "fraud" and "valid" traffic will be opposite in meaning for each label. Here is an example where it gets confusing:

enter image description here

Notice Total, Valid and Ad Fraud rows. Users will see Valid/Total traffic increase as positive, and Fraud increase as negative. I'm concerned for clarity, has anyone dealt with this situation?

Best options seem to be:

  1. Removing the increase/decrease relationships, but it seems to lose the ease of understanding at glance.
  2. Only display the relationship for ad fraud; ad fraud analysis is the main use for our users.
  3. Something else?

Updated: For reference, the focus was given to the forecast comparison as the main use case.

We will be testing with a bar chart as well, in 3 cols - past, current, forecast.
