Invitation to locked Voice Channel is broken visually

I invite someone (via invitation link) to my locked Voice Channel (the invited person is not in the group - has no access)

Working with Discord on Windows. 

-> The link redirects to the main Text channel (on the server) - this is fine.

Now the person enters a (non-locked) voice channel manually. Works of course.

Now the person clicks the invitation link (to the locked channel) again. The invited person sees itself as INSIDE the locked channel. It has a BIG lock icon. In fact, the person is NOT in the channel (I can see her being in the unlocked voice channel)

For me, with appropriate rights, the channel has a Speaker-icon with a SMALL lock. 

So the visualization for the person (that is not assigned a proper role) is wrong sometimes.
