Inverse bolded % at zsh prompt

Question

This is minor but it's driving me crazy.

My prompt is followed by an inverse bolded % like so:

I want it to go away.

I am using: zsh with oh-my-zsh on iterm2

What I have tried:

I found this and according to the accepted answer this is caused by PROPMT_SP as explained in the zsh manual:

Attempt to preserve a partial line (i.e. a line that did not end with a newline) that would otherwise be covered up by the command prompt due to the PROMPT_CR option. This works by outputting some cursor-control characters, including a series of spaces, that should make the terminal wrap to the next line when a partial line is present (note that this is only successful if your terminal has automatic margins, which is typical).

When a partial line is preserved, by default you will see an inverse+bold character at the end of the partial line: a % for a normal user or a # for root. If set, the shell parameter PROMPT_EOL_MARK can be used to customize how the end of partial lines are shown.

Following the accepted answer I entered this into the terminal:

unsetopt PROMPT_SP

and restarted. This didn't work, so I continued to try:

setopt PROMPT_CR
setopt PROMPT_SP
export PROMPT_EOL_MARK=""

and restarted. This didn't work so i added

setopt PROMPT_CR
setopt PROMPT_SP
export PROMPT_EOL_MARK=""

into my ~/.zshrc and restarted this didn't work.

Going down to the other answer: The other answer suggested adding those into your selected .zsh-theme and add the above lines. I did not have one selected and according to this the default theme is robbyrussell.zsh-theme, so I added the above lines into ~/.oh-my-zsh/themes/robbyrussell.zsh-theme and that didn't work. I deleted those lines and changed the theme in my ~/.zshrc to blinks.zsh-theme and added the above lines to ~/.oh-my-zsh/themes/blinks.zsh-theme and restarted and that didn't work.

Once all of this did not work I searched again on Google and only found this which was more of the same solutions that have not worked so far for me.

What am I doing wrong?
