Sorry for the issues you are facing.
There are two issues at play here:
1. Choice fields and the fact that they don't display right values
This is a known issue on PowerApps side and we should have a fix for this released very soon. Until then, please follow the workaround listed on the other thread
https://powerusers.microsoft.com/t5/PowerApps-Forum/Choice-field-fails/m-p/9749#M4321
2. For the other fields in your list (I assume they are Multi-line text fields)
You should be able to swap that with a HtmlText control
Here are steps on how to do that
a. Unlock the control by clicking on the control and going to Advanced view (right-hand-side)

b. Delete the control that displays Html and add a "Html Text" control instead
c. Set HtmlText property of Html control to Parent.Default

After this you should be able to see the contents right. This will ensure all formatting is there.
3. If you are experiencing the same problems on an "Edit form", then you can make the card strip out all Html contents as follows:
a. Select the card control that displays Html Content and change it's "Default" property to be PlainText(ThisItem.FieldName) where FieldName is the field you are interested in. Again, you need to unlock the card to achieve this.
You can follow the same approach for the view form as well (the one in 2 above)
I will file bugs on the PA side so these get done without user intervention. Until then, please follow the workarounds listed here.
Let me know if the instructions are not clear.
Thanks
