Tuviera vs. tuvieses with only one accepted

Question

Hello! Unless I am missing something, I was provided a question in the drop-down where I had to pick the correct conjugation of tener with the imperfect subj. It seems to be that both tuviera and tuvieses should be accepted, however only "tuviera" was. If tuvieses is not accepted, it should not be listed in the drop down. Perhaps you can fix this? Gracias.

Hola Multilingual 1
Both tuviera and tuviese are correct forms of the imperfect subjunctive in Spanish. They are completely interchangeable and it’s up to the speaker which one to use. In this case, you selected the -ra form (tuviera), which is perfectly fine.
So yes, you could have chosen either form and your answer is correct.
