TYPO3 Core

If I create a new element on the page, then I get the error message:
"Wrong configuration in table xxxxxxx"

The foreign_match_fields fieldname is changed to the field name of element.

When I save and edit the element, I can change the file.

If I add a new element the same issues appear.
When I save and edit it again it´s possible to choose a new file.

After saving the element the last selected file is in every element.

So I think there is no relation to each "dynamic" element in the section.

Example flex form:

<dynamic_col type="array">
    <section>1</section>
    <title>Column</title>
    <type>array</type>
    <el type="array">
        <container type="array">
            <type>array</type>
            <el type="array">
                <image type="array">
                    <TCEforms type="array">
