Order revenue is present in DataLayer, doesn’t get loaded in Analytics

So I have tracking of enhanced analytics enabled in plugin settings and when I submit the order, all data layer data is loaded correctly, including the order revenue. However, the revenue doesn’t get loaded by GA.

This is the DataLayer as seen on order-received page by GTM Preview tool:

{
  gtm: {start: 1607064166540, uniqueEventId: 12},
  event: 'gtm.load',
  pagePostType: 'page',
  pagePostType2: 'single-page',
  pagePostAuthor: 'admin',
  ecommerce: {
    currencyCode: 'EUR',
    purchase: {
      actionField: {
        id: '202000037',
        affiliation: '',
        revenue: 33.8,
        tax: 0,
        shipping: 3.9,
        coupon: ''
      },
      products: [
        {
          id: 119206,
          name: '3PACK Klasické pono?ky v dar?ekovej krabi?ke Calvin Kle
                in 100002161 001',
          sku: '8718824988269',
          category: 'So vzorom/obrázkom',
          price: 28.9,
          stocklevel: 4,
          variant: 'uni',
          quantity: 1
        }
      ]
    }
  },
  inputID: 'password',
  inputName: 'password',
  inputClass: 'form-control',
  formID: '(no form ID)',
  formName: '(no form name)',
  formClass: 'login'
}

And this is my revenue variable set in GTM (data layer version 2:

ecommerce.purchase.actionField.revenue

Strange thing I’ve noticed, when I check the data layer conents from Google Tag Assistant on order-received page, the structure is different. Here’s the data layer from tag assistant:

  },
  {

    "gtm.uniqueEventId": 11
  },
  {
    "event": "gtm.load",
    "gtm.uniqueEventId": 12
  }
]

What could be the issue?
Thank you
