It's because scalars(multipliers) are funky as fuck. What is basically happening is that the slow ratio is messing with the speed boost you are getting.

This is a basic jist of how the formula goes:


 * Initial Movement Speed(1+% movement speed boost)(1-% movement speed slow)=Final Movement Speed

So when you are hit with something like a and throw a rank 4  on yourself with 335 initial movement speed, it looks like this:

$$325(1.85)(0.6)=360.75$$

Also, the order doesn't matter between the haste or the slow due to the Associative Property of Multiplication--as you can see here:

$$\left( 325 \times 1.85 \right) \left( 0.6 \right) = 601.25 \times 0.6 = 360.75$$ $$\left( 325 \times 0.6 \right) \left( 1.85 \right) = 195 \times 1.85 = 360.75$$

In the end, what is happening is that the slow is greatly interfering with the speed boost by transforming what should be an 85% speed boost into an 11% speed boost. It works this way because in the formula you add 1 by the speed boost which causes the speed decrease to become extremely steep.

$$325 \left( 1.85 \times 0.6 \right) = 325 \times 1.11 = 360.75$$
