Gap 100% - Best bound 0

I have developed a model for my master thesis. The model runs and finds some integer solutions (these solutions are actually valid solutions), yet no optimal solution is found. The problem is that the best bound is always equal to 0, this leads to the value of the gap equal to 100% (the best solution is equal to 24.75). My question is whether this is a problem or not, and whether there is a way to increase the value of the best bound.

It seems to me that the problem is that there is no lower bound to the problem. For this reason, the best bound is not calculated. But I will leave it to you guys.

Thank you for all your help
