Version 5.4.12 will not read files that Version 5.1.6.2 will

I have files prepared using Word that are docx, doc and odt. Using ubuntu/libre ver 5.1.6.2 I can read them but not using Ubuntu/libre 5.4.1.2. I upgraded my 5.4.1.2 to 5.4.2.2 and there is no improvement.
Something seems to have been lost in development. Please suggest a fix for this.

Nothing can be said without seeing a sample file. Please file a bug report and provide the sample, to enable developers to “suggest a fix for this”.
