Pin Map doesn't show any tooltip

I have a map that it takes a few seconds to load and refresh, but that's expected.
But the pins, don't have any tooltip information, and they don't look like the "ballon" shape I see in the documentation, I see small squares instead without any info.

Is this expected?

Plus the 3-4 columns are fairly straightforward small text and numbers (nothing weird).

Please send diagnostic info, also post the logs from the browser when seeing the tooltip
