Reproduction steps:

1) Start the server login as Admin
2) Go to left Product Navigation Menu > Liferay DXP site > Content > Web Content
3) Click on the top-right three vertical dots and choose "Structure"
4) Click on the + button to add a new structure
5) Create a new structure made by an out of the box Image field, for example:

{
    "availableLanguageIds": [
        "en_US"
    ],
    "defaultLanguageId": "en_US",
    "fields": [
        {
            "label": {
                "en_US": "Afbeelding"
            },
            "predefinedValue": {
                "en_US": ""
            },
            "style": {
                "en_US": ""
            },
            "tip": {
                "en_US": ""
            },
            "dataType": "image",
            "fieldNamespace": "ddm",
            "indexType": "text",
            "localizable": true,
            "name": "Afbeelding39wk",
            "readOnly": false,
            "repeatable": true,
            "required": false,
            "showLabel": true,
            "type": "ddm-image"
        }
    ]
}

6) Save and associate a new, blank, dummy template to it so it will be possible to publish web contents from such structure
7) Go to Control Panel > Configuration > System Settings > Documents and Media > Service > Maximum File Size, add 3072000
8) Go on the DXP Welcome page, click on the top-right + icon > Applications > Highlighted > Web Content Display > Add it to the page
9) Click on the top-right + icon in the portlet itself to add a new web content from the structure made at step 4/5
10) In the Image field, click on the "Select" button > "Select File" button > Choose an image that is more than 3MB in size

Actual behavior: There will be an error message saying "Please enter a file with a valid file size no larger than 100.0MB."
Expected: The message to be "Please enter a file with a valid file size no larger than 3MB."
