Hi Mimi_s_Mum :-)
Forgive me for trying to answer although I am neither an academic, nor
an expert on the naming of neuropsychological disorders, nor a clincian of any sort.

I suggest you call it, Language-specific Broca's (speech-production) aphasia.
Or even that it might be called the same except for making the description
more specific by changing it to "English-specific.[etc]".

That is a sign - as far as I can 'intuit it' - of the fact that different languages
(as different as e.g. Japanense and English) are learnt (finally coded and produced
and phonetically decoded) in 'separate enough' speech preparing (decoding/coding) cortical places.
This would make the time it takes to switch long enough for only the
phonetic decoding/understanding process to be completed in short enough time
for you to not detect any problem in this regard, but it would take so much longer
time for the speech coding/outputting part of the process of verbal communication to
reach completion that the _in parallel operating_ mismatch-monitoring function (aspect of
what your brain does) gets activated enough to make you aware of this 'problem'.
