Why depreciation of a fully depreciated asset continues when sold in V13

when upgraded from v12 to v13 , we noticed that when selling “a fully depreciated fixed asset” , the depreciation continues and values the asset with a negative value.
this practice has never occured in v12, and when asset was sold after being fully depreciated, the depreciation table of the asset is not affected and stops after having reached a value of zero, which is good and normal . In v13, once the selling transaction takes place, another line in the depreciation table is added and makes the asset value with negative !!! any explanation or a way to stop this … thank you.
