It sounds like you have forgotten to enclose non-printing characters
in your prompt with \[...\].

The bash manual says:
PROMPTING
\[ begin a sequence of non-printing characters, which could
be used to embed a terminal control sequence into the
prompt
\] end a sequence of non-printing characters
Therefore you want something like:
_CRed="$(echo -en "\033[31m")" #Red
_CRST="$(echo -en "\033[0m")" #Reset
_CBLD="$(echo -en "\033[1m")" #Bold
export _prompt_open=""
export _prompt_close=">"
[[ $UID -eq 1000 ]] && {
_prompt_open="$_CBLD$_CRed"
_prompt_close="#$_CRST"
}
export PS1='\[${_prompt_open}\]$(pwd "$PWD")\[${_prompt_close}\] ';
But I didn't test the above.
