I just activated taproot on my node and I see this on softforks

Describe the bug

I updated to taproot on my node (core v.0.21.1) and now the soft forks section shows an unparsed json instead of the other soft forks.

Environment (please complete the following information):

Bitcoin Core / Node Version [0.21.1]
NodeJS Version [npm -version = 6.14.10]
Browser [TOR browser]
Code Version / Commit [version: 3.0.0, commit: 8c10489f23, released: 2021-04-08]
Installation Method [raspiBlitz]

To Reproduce

Steps to reproduce the behavior:

Update node to bitcoin core 0.21.1 (taproot)
Open bitcoin explorer with TOR: http://xxxx.onion/node-details

The soft forks section shows:

taproot
bip9 - {"status":"locked_in","start_time":1619222400,"timeout":1628640000,"since":687456,"min_activation_height":709632}

Instead of properly formatted like other soft forks

The JSON output shows the difference:
