Flood Lights Flickering/Dropping Out

Hello, I’m looking for some advice on my current issue. Here is my setup:

Controller: GL-C-017WL-D

Power Supply: Evertech 18 Channel Port 12V DC 10 Amp Amper

LEDs: WS2811 Flood lights

Data booster: GL-BS-001WL

I am having flickering issues when set to solid RGB colors. When set to white (full RGB) they flicker and then fade to a dim red. I am powering the controller using one fuse from the power supply. Then injecting power in between each flood light. I also have a data booster after the controller. I think it may be voltage drop over the 8 flood lights being on only 4 fuses. But any advice would be appreciated.
