Why does getting a single block in NEO prevent getting the remainder of the blocks?

I have blocks set up for nutritional values: Calories, Total Fat, Carbohydrates, etc. These are set up in NEO blocks.

I can successfully loop through all of the NEO blocks (about 20 rows total) and output the content using this for loop:

{% for block in entry.nutritionBuilder.level(1).all() %}
    ...
{% endfor %}

Later, I added a line ABOVE this loop to retrieve the content of a single block:

{% set item = entry.nutritionBuilder.type('blockCalories').one() %}
{{ item.nutritionValue }}

This works, in that it will output the value I need to retrieve. However, the for loop below this line now only outputs a single row from nutritionBuilder which is blockCalories row.

Can anyone see why this is happening?

{% set blocks = entry.nutritionBuilder %}

{% set item = clone(blocks).type('blockCalories').one() %}
{{ item.nutritionValue }}

{% for block in clone(blocks).level(1).all() %}
    ...
{% endfor %}

{% set blocks = entry.nutritionBuilder %}

{% set item = clone(blocks).type('blockCalories').one() %}
{{ item.nutrionValue }}

{% for block in clone(blocks).level(1).all() %}
...
{% endfor %}
