That leaves us knowing that something in the active text formatters is allowing the incorrect HTML through or adding it in.
If it was used in conjunction with a 'truncate' what you could end up with was something trying to be output then being cut-off.
Always best to deal with one thing at a time, so pick one problem and only deal with that until its fixed.
Perhaps start with the action timeline issue.

So you have the action timeline issue, the problem is not there when all the active text formatters are turned off, turn them back on one-by-one until the error appears again. That will let you know which one is causing the error.
Once you know that then you can try to locate the source template of the error where the Active Text Formatter is being applied. Once you know that then you can see if any other things are being applied in that location to that variable and perhaps change the order of them. Or block that Active Text Formatter in that location.
