You have misspelling in your template for languageknowledge
variable.
Change this line:
{% for languageknowlege in languageknowledge_list %}
<li>{{ languageknowledge.language }}, h2 got it,</li>
To:
{% for languageknowledge in languageknowledge_list %}
<li>{{ languageknowledge.language }}, h2 got it,</li>
Note that it’s better to using good ide
that at least have spell checker, also separate your name of variables by _
when are combinatorial, for example using language_knowledge
instead of languageknowledge
to help spell checker to better detect typo.
