Question about seals into pets.

Hi. I just bought two Mysterious Tishanan seals to turn into pets. But when I tried to extract them it says the familiars maximum level is higher than mine so i cannot extract it. I'm lvl 50 and its max level is 60. The max level of every legenday familiar I have gotten in this game from events or deals had a higher max level than me so why does a seal suddeniy become an issue? The research I obtained says the pet will be level 1 after I extract it. So what is this restriction?? What am I msssing?

Thanks in advance
