Netlify Trailing Slash

My website is in Prismic and I use Netlify server to deploy it. The problem I get is a '/' (trailing slash) issue with URLs. Issues is in steps below -

Step 1 - On clicks, URLs (internal page) are opening "without /" at the end.

Step 2 - URLs are redirecting to "with /" at the end.

Step 3 - URLs are again redirecting to "without /" at the end.

This causes me a lot of issue in terms of redirection, duplicate URLs, etc.

If someone already has experienced this issue and fixed, please help me. FYI - My website is https://www.gspann.com/

Thanks in Advance.
