Issue when filtering using a lower-then...

There seems to be an issue when filtering {articles} using a lower-then evaluation on a custom calendar-field.

LESS-THEN EVALUATION: NOT OKAY
I have a custom calendar-field "datum-eerste -voorstelling". I want to filter articles that have date in the past:
'datum-eerste-voorstelling < today' using this syntax:Detail: when saving article the editor Code Mirror messes up syntax highligting

Outcome is not as expected: article titles are displayed but they are not seperated by an "</br>"and they don't meet the criterium (some don't have the custom calendar-field that is being used as a filter, but are displayed anyway).

GREATER-THEN EVALUATION: OKAY
When I use a greater-then evaluation with this code:The outcome is as expected
Detail: when saving article the editor Code Mirror does the syntax highligting properly.

Error: 0 DateTime::__construct(): Failed to parse time string (today')\&quot; datum-eerste-uitvoering\=\&quot;&gt;date('today) at position 5 ('): Unexpected character
