Hashtag in URL

The scenario is that I am posting form data to a URL that has an existing hash tag in the URL. Unbounce treats this Hashtag as anchor and moves the hash tag to the end of the URL once its posted

Example URL to be posted to
https://dx.mysite.com/dx/MNDX/#/date-selection

Once Unbouce sends the form data to the URL

https://dx.mysite.com/dx/MNDX/?journeyType=round-trip&origin=JNB&destination=CPT&date=11-30-2019&date1=12-28-2019&ADT=1&CHD=0&INF=0&class=economy&pointOfSale=ZA&execution=e1s1#/date-selection

As you can see Unbouce has taken the # and trailing url and placed it at the end of the URL, thus breaking my page

Any ideas how I can circumvent this issue?
