Insignificant from T-ratio but why the attribute importance is high?

I did Latent Class analysis, in one group..the T-ratio from all the level of an attribute turns to be insignificant. However, the attribute importance of that level is at a high number (2nd rank when comparing with other groups). I wonder why?

Also, does this means once it turns to be significant.. the preferred attribute level and attribute importance cannot be interpret?

Thank you so much!
