What is the real PayPal account balance?

Question

PayPal

Previously, I only paid through it from the linked card, but now I transferred money in $ to the account itself 1 time.
Who uses, explain to me, here in the history it is written:
Gross amount 2.65 USD
Commission 0.00 USD
Net amount + 2.65 USD
Balance 2.65 USD
but on the main page of the account:
PayPal account balance
2.46 USD Available balance
Currencies
0.00 USD
149.10 RUB
First, where did a few cents go, even if the commission is clearly written 0?
second, why is 0.00 USD written below? I switched some option there before, so that there was no conversion to the country's currency, but as I understand it, it did not help.
