PSoC 5LP has both fixed function and UDB based I2C implementation. In the component, please make sure that the fixed function block is selected by checking the fixed function radio button as shown in the picture
Thanks and regards

91.7% is a lot! Most scarce PSoC resource is, actually, routing. It is likely that fitter can't make a path to connect FF I2C (in and out).
Thanks. It may well be routing, just a bit confusing that it complains about UDB then.
I agree with /odissey1-san.
When I tried creating a project which has only 1 I2C, the UDB usage was 0.
So I suspect that the existence of the added I2C with pin routing interfering.
Although it may not help, but I would try some pin combination of I2C
so that there may be routes which will not interfere.
Or if possible, I would un-check all pin-assignments in Pins
and use generate application to let PSoC Creator try its best.
