Water tank will not fill

We are first time RV owners of a 2019 Passport 2200RBWE. We spent a fair amount of time camping this summer and are getting comfortable with the trailer and towing.

What we cannot seem to figure out is the fresh water tank. After filling the LED never shows more than 1/3 full. I had been thinking that it is a problem with the gauge but our past trip we ran out of water very quickly and had to pour gallons of water in manually. So it seems that the water tank is not getting full when we add water.

Any one have ideas as to what is going on?

Is it possible you have an air exit tube that has become blocked, and you are trying to fill into a big air bubble?

I've had experience where the fill tube gets an air lock. I'll rock the trailer a little which usually clears it. Also use on of these: https://www.walmart.com/ip/Water-Fil...yABEgKrR_D_BwE

Never had a problem since using the Water Fill on the hose. Works great with an in-line filter.

Our tank "burps" about 2 times when filling, so we let it burp and then start filling again until the water starts spilling out "differently" - seems we can tell, just can't explain it!
