My PNG-SNOB Pair's Liquidity doesn't appear

Hello everyone,
I’ve added liquidity to PNG-SNOB pair, and deposited my PGL tokens to the PNG pool but my liquidity appears 0 $ in positions (on page) and i am not earning fees.
Thanks in advance.
Best Regards.

Of course i can’t withdraw my liquidity too (no remove button since the total is 0 $)

After i’ve withdrew PGL tokens, i was able to withdraw (remove button showed up on the positions page). There is no problem for adding and removing liquidity.
