[Resolved] Advanced translator not working properly, reverting to englsih on frontend

I also was getting error an message,
"Translation not saved
The original text contains nested formatting tags (one tag inside another).
Please nest the formatting markers in your translation in the same order."

The original text is no different than other pieces of text.

Sometimes the editor breaks original sentences apart, so the translation is a piece of a sentence at a time. Again the original text is no different than elsewhere.

Not sure if anything was done on the backend by WPML.
I re-translated the entire page from the translations section of the WPML menu. This created a better translation, and all sections now were in French. It appears to have learned from my previous corrections. Also I selected to "publish without needing review."

Here is one big difficulty or bug in the translation editor...
when translating an English phrase that was in bold, it may often be split into two bolded words separated by a non-bolded word or two when in French. When this happened there were then more bolded areas in the French translation than in the English original. The translation editor would not accept this. When I made sure there were an equal number of bolded areas in the original English and in the French translation the sentence would be accepted.

This is a bug that needs to be corrected. Very confusing, and not necessary.

Thank you Christopher for suggesting using the previous editor version as it stated reasons why the sentence would not be accepted. Even though the explanations were not very clear it gave me something to go on.

The suggestion (by WPML) to update the plugins was not helpful as the versions suggested to upgrade to were not available.
