9.2 to 11.2 dashboard display issue

I have a bit of an issue with display of mixed text and bignumber cards since I updated to 11.2
Heres is a sample of the old display (release 9.2):


and a sample of after (release 11.2):

and the custom code:

type: custom:layout-card
layout_type: grid
layout:
  grid-template-columns: 316px 316px 316px 316px
  grid-template-rows: 176px 176px 176px 176px 76px
  grid-template-areas: |
    "L1 L1 R1 R1"
    "L2 L2 WS rT"
    "oT pT WS rG"
    "a4 pT SM d4"
    "fL fL fL fR"
cards:
  - type: custom:stack-in-card
    mode: horizontal
    view_layout:
      grid-area: L1
    cards:
      - type: custom:bignumber-card
        style: |
          ha-card {
            padding: 0px 0px 0px 8px;
            text-align: right;
            margin-right: 40px;
            font-Weight: bold;
          }
        scale: 118px
        entity: sensor.outdoor_temperature
        hideunit: true
      - type: custom:stack-in-card
        mode: vertical
        cards:
          - type: markdown
            style: |
              ha-card {
                padding: 0px 0px 0px 0px;
                margin-top: 0px;
                font-size: 24px;
                height: 74px !important;
              }
            content: |
              # <center>Outdoors</center>
          - type: custom:bignumber-card
            style: |
              ha-card {
                padding: 0px 00px 40px 00px;
                margin-left: 00px;
                height: 56px !important;
                font-Weight: 600;
              }
            scale: 70px
            entity: sensor.humidity
            hideunit: false

Obviously, something changed, or I was doing something that was not correct, but worked.
I also updated all the custom components.
I have a number of these (and similar cards) in a grid display for monitoring weather conditions.
Any suggestions?
